dziwitsani:
Polyvinyl chloride resin, yomwe imadziwika kuti PVC resin, ndi polima polima kuchokera ku vinyl chloride monomer (VCM).Chifukwa cha zinthu zosiyanasiyana komanso zolimba, utomoni wa PVC umagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikiza zaumoyo.Mu blog iyi, tiwona kufunikira kwa utomoni wa PVC ngati mankhwala ndikumvetsetsa momwe zinthu monga ma polymerization process, machitidwe amachitidwe, kapangidwe ka reactant ndi zowonjezera zimakhudzira magwiridwe ake.

Polyvinyl chloride resin: kuyang'anitsitsa
Utoto wa PVC umapangidwa ndi polymerizing vinyl chloride monomer, njira yomwe imapanga unyolo wautali wazinthu zamapangidwe CH2-CHCl.Mlingo wa polymerization, nthawi zambiri 590 mpaka 1500, umathandizira kukulitsa mphamvu ndi kulimba kwa zinthuzo.

Mapulogalamu azachipatala
PVC utomoni chimagwiritsidwa ntchito m'mafakitale azachipatala chifukwa katundu wake kwambiri.Amagwiritsidwa ntchito popanga zida zamankhwala monga machubu olowera m'mitsempha, matumba amagazi, ma catheter ndi magolovesi opangira opaleshoni.Kusinthasintha kwa utomoni wa PVC, kumveka bwino, komanso kukana kwamankhwala kumapangitsa kuti ikhale yabwino pazachipatala.

Zinthu zomwe zimakhudza magwiridwe antchito a utomoni wa PVC
Kuchita kwa utomoni wa PVC kumasiyana malinga ndi zinthu zosiyanasiyana.Njira ya polymerization imagwira ntchito yofunika kwambiri pakuzindikira kulemera kwa maselo ndi kuchuluka kwa polymerization.Zomwe zimachitika, monga kutentha ndi kupanikizika, zimakhudzanso katundu wa chinthu chomaliza.Kuphatikiza apo, mapangidwe a reactants ndi kuwonjezera kwa zowonjezera zimatha kusinthanso mawonekedwe a utomoni kuti akwaniritse zofunikira zachipatala.

Zowonjezera mu PVC resin
Zowonjezera nthawi zambiri zimawonjezeredwa ku utomoni wa PVC kuti uwonjezere katundu wina.Mwachitsanzo, mapulasitiki amatha kuwonjezera kusinthasintha, kupanga zipangizo zoyenera kwambiri zogwiritsira ntchito zomwe zimafuna kusuntha ndi kupindika.Kuwonjezera zolimbitsa thupi kumatha kukulitsa kukana kutentha ndi kukana kuwala kwa utomoni ndikuwonetsetsa moyo wake wautumiki.Zowonjezera zina ndi monga zosinthira mphamvu, mafuta odzola ndi zodzaza, zonse zimathandizira kukonza magwiridwe antchito ndi magwiridwe antchito.

Pomaliza:
Polyvinyl chloride resin, kapena utomoni wa PVC, ukupitilizabe kukhala chinthu chofunikira kwambiri pazachipatala.Kusinthasintha kwake, mphamvu ndi kukana kwa mankhwala kumapangitsa kukhala chinthu chosankhidwa pazida zamankhwala.Kumvetsetsa kukhudzika kwa zinthu monga njira ya polymerization, momwe zimachitikira, mawonekedwe a reactant ndi zowonjezera ndizofunikira kuti mupange utomoni wa PVC wokhala ndi zinthu zomwe mukufuna.Pamene teknoloji ikupita patsogolo, kupititsa patsogolo kwa PVC resin mosakayika kudzasintha tsogolo lazachipatala, ndipo pamapeto pake zidzapindulitsa odwala ndi opereka chithandizo chamankhwala.
