The zosungunulira P4 specifications, kapangidwe

Pakuti bwino ntchito kupenta alinso adjuvants zofunika monga solvents, amene ntchito ndi zofunika kukonzeketsera pamwamba ndi kugawira kugwirizana Napempha kwa zipangizo utoto. M'nkhani ino tikambirana P4 zosungunulira, yemwe ali mmodzi wa anthu otchuka ndi odziwika mu msika wa zipangizo zofanana.

makhalidwe General

P4 zosungunulira - ndi zosungunulira organic umene uli bwino colorless madzi (nthawi zina amakhala ndi kulocha chikasu) popanda particles kuonekera inaimitsidwa. Iwo yodziwika ndi fungo yeniyeni ndi mkulu osakhalitsa. Mtengo avareji osalimba wachibale wa thunthu ndi 0,85 ga pa CC. cm. autoignites pa kutentha madigiri 550. Zinabala malinga imene inafotokozedwa GOST 7827-74 mfundo. Yopangidwa mu chidebe mafakitale - pulasitiki ndipo muli galasi (mabotolo) zamitundu yosiyanasiyana.

P4 zosungunulira: zikuchokera

P4 - osakaniza mankhwala atatu organic, amene pamodzi tipeze dzuwa kwambiri. Pamafunikanso zinthu zotsatirazi:

• Toluene - 62%;

• acetone - 26%;

• butyl nthochi - 12%.

Chifukwa zikuchokera izi zosungunulira okwanira ali katundu zabwino ogula ndi mkulu Mwachangu yanyumba vanishi ndi utoto. Chotero pophika monga butyl nthochi, kumaonjezera gloss mafilimu ntchito zokutira ndiponso kupewa whitening ndi oyeretsa.

Waukulu magawo luso zosungunulira ndi

The P4 zosungunulira (GOST 7827-74) Anali ndi makhalidwe awa:

• chizindikiro mtengo osakhalitsa wa ethyl efa mu osiyanasiyana kuchokera 5 mpaka 15;

• coagulation nambala osachepera 24%;

• chiwerengero cha madzi (by misa) si kuposa 0,7%;

• asidi chiwerengero cha osapitirira 0,07 mg wa KOH / g.

Zilipo ngati zosungunulira kalasi P-4A. The reagent ndi zosungunulira P4 - analogs wa specifications. Komabe, iwo osiyana mu zikuchokera, chifukwa malinga ndi zofunikira za GOST, mu P-4A simaphatikiza butyl nthochi. Kusiyana kwina ndi zizindikiro izi kuti mtundu zosungunulira F-4A, mosiyana P4 akhoza kuyimisa enamel CHV 124 (kumatenda ndi imvi).

Mmene zosungunulira ntchito P4?

The reagent ntchito kuswana kwa utoto lembani PSC PSC Ln ndi LS, maziko kupanga amene chlorinated polyvinyl mankhwala enaake resins, resins epoxy, vinilu kolorayidi copolymers ndi ena zinthu zina filimu-n'kupanga.

N'zimene - mmene kuchepetsa utoto zosungunulira P4?

P4 zosungunulira anawonjezera mu zinthu zina (varnish kapena utoto) mu zigawo wamng'ono mpaka kugwirizana ankafuna. Ayipanga utoto (lacquer) pamafunika yogwira zonse.

Kuthira okonzeka ❖ kuyanika zosungunulira ukuphwera ndi filimu-kupanga zinthu alimbitse, osatembenukira ku ❖ kuyanika ndi zoteteza. Nkofunika pamene ntchito ndi zosungunulira kupewa ingress madzi kukhala mbali ya acetone mwina kusakaniza mosavuta ndi izo, ndipo kuchita zimenezi kungachititse kuti kupotoza mtundu kapena whitening wa chovala bwino.

tipewe ngozi pamene akugwira P4 zosungunulira

Tiyenera kukumbukira kuti zinthu ali toxicant ndi mwina kungasokoneze pa thupi la munthu, omwe umaperekedwa ndi inhalation, ndi likulowerera khungu. Ndi yaitali kukhudzana zotheka zoyipa za zosungunulira pa za mafupa ndi magazi. Pankhani ya kukhudzana yaitali ndi khungu ungadzakhazikitsidwe dermatitis.

Tangoganizirani pamwamba, ndi P4 zosungunulira ayenera kuchitidwa pa malo a, kupereka mpweya wabwino. Ndi kofunika kugwiritsa ntchito zinthu zodzitetezera kuti kupewa kukhudzana ndi zinthu zoipa mu dongosolo kupuma, maso ndi khungu la manja (makina, magolovesi, Goggles).

P4, komanso angapo mankhwala ena, yodziwika ndi digiri yapamwamba ya ngozi moto. osakaniza mosavuta akayaka, ndipo, mopitirira, ndi zachiwawa. Mabanja amapanga zinthu katundu kusonkhanitsa zosungunulira komanso ndi zachiwawa. Choncho, chofunika zosungunulira ndi kutsatira zofuna chitetezo moto.
