MDF: icho chiri ndi mmene kugwiritsa ntchito zinthu izi?

Mu kukonza ndiponso kumanga nyumba zogona ntchito kwambiri zipangizo, koma mwa iwo alipo amene anazibisa okha ndi ulemerero chosafota chabe. Mwachitsanzo, a chipboard. Ndi chiyani icho?

dzina zikuimirira "Fiberboard". Nkhanizi pepala, kusindikiza umene kumachitika mwa psinjika tchipisi nkhuni ndi Kuwonjezera zosiyanasiyana zigawo zikuluzikulu kumanga.

Monga ulamuliro, mu thupi atsopano a resins kupanga polymeric ntchito. Komanso, monga zinthu zosiyanasiyana, conferring katundu hydrophobic nkhani yotsirizidwa.

Yotsika mtengo (ndipo choncho zambiri ntchito) ceresin ndi paraffin. Nthawi zambiri, gawo la anawonjezera antiseptic zowonjezera. Chifukwa cha iwo, muchikombole pafupifupi amamera fiberboard. Ndi chiyani icho? Nthawi zambiri, monga antiseptic zina ndi phenols, amene bwino kupewa chitukuko cha bowa ndi kuwononga spores awo.

Yopangidwa fibreboard njira ziwiri: youma ndi yonyowa. Komabe, pali njira posachedwapa wapakatikati: konyowa-youma ndi theka-youma.

The njira yotsika mtengo youma pamene fiberboard (icho chiri, ife tanena) aumbike ku tchipisi nkhuni zinthu zachilendo ndipo popanda wetting ndi madzi. Imachepa mbale imachitika pa kutentha ndi anzawo.

Nkhani chifukwa amakhala ndi mtengo wotsika, ndiponso chomasuka porosity kwambiri. wokhutira chinyezi ndi 6-8 kokha%.

M'madzi njira tichipeza magawo yomweyo, koma mu kukanikiza wa zodulidwa nkhuni watumidwa, pokhala titanyowa ndi madzi. Pa exiting atolankhani chipinda chuma kusema mapepala munthu ndipo anatumizidwa ku choumitsira lapansi. Chotero fiberboard mapanelo kale chinyezi mkati 70%. chifukwa iwo amasiyana kulemera kwambiri, koma cholimba.

The njira theka-youma ndi lofanana ndi njira yoyamba tafotokozazi. Kusiyana komwe kulipo ndi asanakhale ntchito kwa swarf yaying'ono yothiriridwa ndi madzi kuti mnyontho nkhani chifukwa ndi 16-18%.

Konyowa-youma njira isiyana onse pamwamba kuti Chip loyamba la mbale madzi impregnated aumbike, ndiye kudyetsedwa kwa choumitsira ndiyeno yekha anatumiza kwa wosachedwa kukanikiza ndondomeko. Chifukwa ndi plywood fiberboard, chinyezi wachibale amene pafupifupi 0%.

Onani kuti sitikuyenda zoonadi, kunena za "tchipisi". chakuti tchipisi mwa makina wapadera, choyamba akusisita ulusi umene kale anapanga ndi mapanelo wokonzeka nsalu.

M'zaka zaposachedwapa zambiri amagwiritsidwa ntchito fiberboard sanitized. Mu kupanga mapanelo ngati padziko awo ali ndi ❖ kuyanika multilayer. Mu mbale choyamba gawo ali ndi wapadera wosanjikiza phunziroli, kupanga maziko olimba. Iwo kusindikizidwa chitsanzo, kutengera pamwamba alipidwa nkhuni.

mbaula ili pafupi musawope chinyezi ndi kumva kuwawa. Pamwamba oipa mu nkhani iyi, ndi varnish wapadera.

Kotero ife ndinakuuzani inu za fiberboard. Kodi izo, tsopano inu mukudziwa. Chifukwa cheapness zakuthupi ndi mphamvu katundu amagwiritsidwa ntchito kawirikawiri osati mipando, komanso zomangamanga.
