Chifukwa chiyani zinthu zina zapulasitiki zimanunkhiza?

M'moyo watsiku ndi tsiku, tidzapeza kuti zinthu zambiri zapulasitiki zimakhala ndi fungo zikayamba kugwiritsidwa ntchito.Mwachitsanzo, zinthu zina zodziwika bwino za polyethylene ndi polypropylene zimakhala ndi fungo lautsi kumayambiriro kwa ntchito, ndipo fungo lidzakhala lochepa kwambiri pakapita nthawi., Chifukwa chiyani mapulasitikiwa amanunkhiza?

Zonunkhira izi m'mapulasitiki makamaka zimachokera ku zowonjezera zomwe zimawonjezeredwa popanga pulasitiki.Izi ndi chifukwa cha Kuwonjezera kwa solvents ndi pang'ono intiators ndi zina zina pa polymerization wa polyethylene ndi polypropylene utomoni.Pambuyo kutsuka, kusefera, ndi zina zotero, nthawi zina zochepa zothandizira zomwe tatchulazi zidzatsalira, ndipo kuwonjezera apo, polima yocheperako yolemera kwambiri imakhalabe mu resin.Panthawi yopangira ndi kukonza zinthu zapulasitiki, zinthuzi zidzawonekera kutentha kwambiri kuti zithawe fungo losazolowereka ndikukhala pamwamba pa mankhwalawa.
Kuphatikiza apo, opanga ena amawonjezera turpentine ngati chida chodaya popaka utoto wapulasitiki.Ngati imagwiritsidwa ntchito kwambiri, fungo la turpentine lidzathawanso kuchokera ku mankhwalawa.Zimatha pang'onopang'ono ndipo zilibe mphamvu pa thanzi la munthu.Komabe, ngati fungo lili lolemera kwambiri ndipo limakhalapo kwa nthawi yaitali, lidzakhudzabe thanzi la munthu.
Chifukwa chake, pogula zinthu zapulasitiki, tiyenera kusankha zinthu zapulasitiki zokhala ndi zida zotetezeka, zabwino komanso chitetezo chapamwamba.
