Amorphous zipangizo. Tinthu ndi amorphous boma la nkhaniyi. The ntchito zinthu amorphous

Kodi munaganizapo kodi enigmatic amorphous mankhwala? Pakuti iwo amapanga wosiyana onse olimba ndi ku madzi. Popeza kuti matupi amenewa ali makamaka boma condensed, ndi kokha kuti yochepa osiyanasiyana. Zitsanzo zipangizo amorphous - utomoni, galasi, Amber, labala, polyethylene, polyvinyl mankhwala enaake (PVC mazenera ankakonda athu), ndi zina ma polima zosiyanasiyana. Ichi ndi thupi lolimba, amene mulibe latisi krustalo. Koma iwo monga sera, zomatira zosiyanasiyana, labala mwakhama ndi mapulasitiki.

The zachilendo katundu zinthu amorphous

Pa akuwaza mu matupi amorphous sumangoyambika nkhope. Tinthu ndithu chosokonekera ndipo pafupi wina ndi mnzake. Iwo akhoza kukhala kwambiri wandiweyani ndi viscous. Kodi iwo ali ndi makhalidwe awo? Mchikakamizo cha kutentha zosiyanasiyana za thupi akuyenda monga madzimadzi, ndipo nthawi yomweyo ndithu zotanuka. Pamene kanthu kunja nthawi yochepa, kapangidwe amorphous wa thunthu pansi kothandiza kwambiri akhoza unagawanika mu zidutswa. Chokhalitsa amadza kuchokera kunja kumabweretsa chakuti iwo mophweka ikuyenda.

Yesani amathera kuyesera pang'ono kunyumba ndi ntchito utomoni. Nachiyika pa pamwamba kwambiri ndipo inu mungazindikire kuti umayamba kuyenda bwino. Ndiko kulondola, chifukwa ndi amorphous! Liwiro zimadalira zizindikiro kutentha. Ngati adzakhala kwambiri, utomoni uyamba kuyenda mofulumira kwambiri.

Kodi wina ndi khalidwe la matupi amenewa? Iwo akhoza kutenga mtundu uliwonse. Ngati amorphous thunthu mu mawonekedwe a particles anaikidwa chotengera kochepa, monga mtsuko kuti iwo afanane ndi chotengeracho. Koma iwo ali isotropic, ie iwo kuonetsa yemweyo thupi katundu mu njira zonse.

Limatsogolera ndi kusintha m'maboma ena. Zitsulo ndi galasi

Boma amorphous wa nkhani sinafike kukhalabe kutentha zina. Pamlingo wochepa atapanga thupi pa mkulu - kusungunula. Zodabwitsa ndizakuti, izo zimatengera pa kukhuthala ndi mlingo wa zinthu zina. Low kutentha amakonda otsika kukhuthala, mkulu M'malo mwake, zolemera.

Pakuti zinthu za mtundu wa amorphous tingaone wina zambiri Mbali - kusintha kwa boma crystalline ndi lachibadwa. Zachitikiranji zimenezi? The mphamvu mkati mwa thupi kuli crystalline kuposa amorphous. Titha kuona chitsanzo cha mankhwala galasi - galasi pamapeto pake Akhristuwo.

Zachitsulo galasi - ndichiyani? Zitsulo akhoza kuthetsa kophimba galasi pa kusungunuka kwa, i.e. chinthu amorphous kupanga dongosolo kunyezimira. Pa solidification ndi yozizira yokumba galasi latisi aumbike kachiwiri. Amorphous zitsulo ali ndi kukana chidwi ndi dzimbiri. Mwachitsanzo, kuti amlonge thupi la galimoto kuti alibe ntchito zosiyanasiyana zokutira, monga kuti zagonjetsedwa kwa wovulala lachibadwa. zakuthupi Amorphous thupi lake atomiki kapangidwe ali mphamvu kuposa kale lonse, choncho, amorphous chitsulo ungagwiritsidwe ntchito gawo lililonse mafakitale kwathunthu.

Kapangidwe galasi zinthu

Kuti bwino makhalidwe a zitsulo ndi kugwira ntchito ndi iwo, muyenera kudziwa kapangidwe ndi galasi la anthu kapena zinthu zina. Yopanga zitsulo ndi zitsulo sanathe kupeza chitukuko chotero, ngati anthu analibe nzeru zina za kusintha kapangidwe ka kasakaniza wazitsulo, ndi njira ndondomeko ndi makhalidwe ntchito.

Anayi limati ya nkhani

Izo ziri zodziwika bwino kuti pali anayi limati akaphatikiza: olimba, madzi, gaseous, plasma. Olimba amorphous mankhwala kungakhale crystalline. Ndi eg wotero periodicity okhudza malo mu dongosolo la particles. particles awa ali timibulu akhoza kudzapereka nthawi apaulendo. matupi zonse zimene taona mu boma gaseous kapena madzi, n'zotheka kusunga lamulo la tinthu nyansi wachisokonezo. zolimba Amorphous (zitsulo mwachitsanzo mu chikhalidwe zinaphatikizidwa, ebonite, mankhwala galasi, resins) angatchedwe mazira zakumwa mtundu, chifukwa iwo ndi kusintha Tingaone mawonekedwe ngati khalidwe Mbali monga kukhuthala.

Mosiyana ndi zipangizo amorphous kwa mpweya ndi zakumwa

Maonekedwe a plasticity, elasticity, oipa ndi ofanana ndi matupi ambiri. The crystalline ndi amorphous zinthu zambiri adzalandira makhalidwe amenewa, pamene zakumwa ndi mpweya mulibe katundu amenewa. Koma inu mukhoza kuwona kuti iwo amathandiza kuti kusintha buku zotanuka.

Tinthu ndi zipangizo amorphous. katundu makina ndi thupi

ndi crystalline ndi amorphous zipangizo zotani? Monga tanena amorphous akhoza kutchulidwa matupi amene ali kukhuthala yaikulu, ndipo pamene iwo si wamba kutentha fluidity. Koma kutentha M'malo mwake, zimawathandiza kuti loyenda ngati madzi.

Kwathunthu osiyana thunthu la mtundu wa crystalline. zolimba izi ukhoza mfundo kusungunuka, malingana ndi kuthamanga kunja. Kukonzekera timibulu zingatheke ngati madzi ozizira. Ngati mulibe njira zina, tikuona kuti boma madzi ayamba kukhala malo osiyana a crystallization. M'midzi yapafupi malo, mapangidwe olimba. timibulu ochepa kuyamba kugwirizana ndi mzake m'njira wachisokonezo, ndi likukhalira otchedwa polycrystalline. Chotero thupi ndi isotropic.

makhalidwe zinthu

N'chiyani chimachititsa thupi ndi makina zimatha matupi? Kodi zofunika zomangira atomiki, komanso mtundu wa dongosolo krustalo. amaayoni timibulu khalidwe amaayoni kumangidwa, kutanthauza kuti yosalala kusintha kwa atomu wina ndi mzake. Pankhaniyi, mapangidwe zabwino ndi zoipa mlandu particles. Amaayoni akapolo, tikhoza kuona chitsanzo losavuta - mikhalidwe achilendo zosiyanasiyana oxides ndi mchere. Chinthu china timibulu amaayoni - wochepa madutsidwe, koma ntchito zake kwambiri kwambiri pamene usavutike. Mu latisi galasi Tingaone zosiyanasiyana mamolekyulu zosiyana amphamvu atomiki muzikondana.

A zambiri mchere kuti ife tikupeza paliponse mu chilengedwe, ndi dongosolo crystalline. Ndipo amorphous boma la nkhani - izo ndi chikhalidwe mu maonekedwe ake kopambana. Only mu nkhani iyi thupi MAONEKEDWE ENIENI, koma timibulu akhoza kutenga maonekedwe a polyhedra okongola ndi kukhala nkhope mosabisa, komanso njira yatsopano kukongola chodabwitsa ndi chiyero cha zolimba kwambiri.

Kodi makhiristo? Amorphous-crystalline dongosolo

Maonekedwe a matupi amenewa ali mosalekeza kulumikiza anapatsidwa. Mwachitsanzo, kulusolito nthawi zonse amaoneka ngati prism hexagonal. Khalani ndi kuyesera pang'ono. Kutenga galasi ka ndi sodium mchere wa mawonekedwe kiyubiki (mbale) ndi kuziyika izo mu njira yapadera ladzala mmene ndingathere ya mchere chomwecho. M'kupita kwa nthawi, muona kuti thupi akanali yemweyo - izo kachiwiri natenga maonekedwe a kyubu kapena dera, amene ali chibadidwe timibulu a mchere.

Amorphous-crystalline zinthu - matupi awa, amene anyamula onse magawo amorphous ndi crystalline. Kodi zimakhudza katundu zinthu eg zimenezi? Makamaka chiŵerengero osiyana mabuku ndi malo osiyana mu ubale wina ndi mzake. Zitsanzo Common wa zomangira monga zipangizo ceramic, zadothi, ziwiya zadothi galasi. Pagome katundu wa zipangizo ndi dongosolo amorphous-crystalline akadziwa kuti zadothi lili kuchuluka pazipita gawo galasi. Indicators kwanthawi mkati peresenti 40-60 whith. Okhutira wotsikitsitsa tikuona chitsanzo cha kuponyera miyala - osachepera 5 peresenti. Pankhaniyi, ndi apamwamba mayamwidwe madzi ndi matailosi ceramic.

Monga amadziwika, zipangizo mafakitale monga dongo matailosi ceramic, ware mwala ndi galasi-zoumbaumba - ndi amorphous-crystalline zipangizo chifukwa zili kunyezimira gawo pamene makhiristo mu dongosolo lake. Tikumbukenso kuti katundu zakuthupi palokha za zomwe zili mu gawo galasi.

zitsulo amorphous

The ntchito zinthu amorphous anachita ambiri zedi pa zamankhwala. Mwachitsanzo, mofulumira yozizira zitsulo chimagwiritsidwa ntchito opaleshoni. Chifukwa zochitika pa nkhaniyi, anthu ambiri amasamukira paokha pambuyo kuvulala kwambiri. Chinthu ndi thunthu la kapangidwe amorphous ndi biomaterial zotichititsa implantation mu fupa. Chifukwa zomangira wapadera, mbale, zikhomo, zikhomo kukhazikitsa mu fractures kwambiri. Poyamba, opaleshoni zolinga zimenezi anagwiritsa ntchito zitsulo ndi titaniyamu. Only patapita unkachitika kuti zipangizo amorphous kuwola ndinso pang'onopang'ono m'thupi ndipo ndi chinthu chodabwitsa limachititsa kuti achire fupa. Ndiyeno, chinthu m'malo mwa fupa.

Ntchito mtundu amorphous zinthu mu metrology ndi cholondola zimango

Mwatsatanetsatane zimango zachokera mwatsatanetsatane, ndi Choncho amatchedwa. A yofunika kwambiri makamaka mu makampani, komanso metrology, kusewera kopitilira muyeso-yeniyeni ntchito choyezera zida, izi zimathandiza ntchito zipangizo za zolimba amorphous. Chifukwa cha miyezo zolondola ikuchitika zasayansi ndi kafukufuku mabungwe m'munda wa okonza ndi sayansi, pali kupanga mankhwala atsopano, kusintha kwa sayansi.

ma polima

Chitsanzo china ndi mmene angagwiritsire ntchito mfundo amorphous - ndi ma polima. Iwo akhoza pang'onopang'ono kusintha kwa kolimba kwa madzi, pamene ma polima crystalline ndi mfundo limatsogolera osati kutentha olimbikitsa. ndi boma thupi la ma polima amorphous chiyani? Ngati zinthu zimenezi zomwe kutentha otsika, muona kuti adzakhala mu boma kunyezimira ndi kuonetsa katundu wa zolimba. Pang'onopang'ono Kutentha zimalimbikitsa chakuti ma polima kuyamba kupita mu khalidwe la kuchuluka elasticity.

zipangizo Amorphous zitsanzo za zomwe ife atsogozedwa, ntchito kwambiri mu makampani. boma Superelasticity amalola ma polima mwanjira olumala, ndipo boma zimatheka chifukwa kusinthasintha kuchuluka kwa maulalo ndi mamolekyulu. kuwonjezeka kutentha amachititsa zizindikiro kuti polima wakhala kwambiri zotanuka katundu. Iye akuyamba kusamukira ku wapadera madzimadzi ndi viscous boma.

Mukasiya zinthu popanda, ndi samaletsa kuwonjezeka kutentha, polima akuwululidwa kuwonongedwa, kuti ndicho kuwonongeka. boma viscous limasonyeza kuti ziwalo zonse za macromolecules ndi mafoni kwambiri. Pamene loyenda polima molekyulu, kulumikizana osati anaweramuka, komanso pafupi ndi mzake. Intermolecular amadza polima kwasanduka chuma olimba (labala). Chotero ndondomeko amatchedwa makina vitrification. nkhaniyi ankagwiritsa ntchito yopanga mafilimu ndi ulusi.

Kuchokera pa ma polima akhoza kukhala okonzekera polyamides, polyacrylonitriles. Popanga ndi polima film, m'pofunika kulikankhira polima kudzera spinnerets kuti ndi kutsegula kagawo woboola pakati, ndi kuika pa tepi. Choncho chopangidwa zipangizo CD ndi chikhazikitso cha matepi. Ma polima mulinso vanishi zosiyanasiyana (kupanga thovu mu zosungunulira wopanda feteleza), zomatira ndi zinthu zina yolusa ndi nsanganizo (m'munsi utomoni ndi filler a), mapulasitiki.

Mapulogalamu a ma polima

mtundu wa mankhwala amorphous kwambiri walowerera mu miyoyo yathu. Iwo ntchito kulikonse. Njirazi ndi monga:

1. zapansi Various yopangira vanishi, zomatira, mankhwala pulasitiki (phenol formaldehyde utomoni).

2. elastomers kapena rubbers kupanga.
