Polyvinyl chloride resin, eo hangata e tsejoang e le PVC resin, ke motsoako oa polymer o entsoeng ka polymerized ho tloha vinyl chloride monomer (VCM). Ka lebaka la thepa ea eona e feto-fetohang le e matla, resin ea PVC e sebelisoa haholo liindastering tse fapaneng, ho kenyeletsoa le tsa bophelo bo botle. Ho blog ena, re tla hlahloba bohlokoa ba resin ea PVC e le motsoako oa bongaka le ho utloisisa hore na lintlha tse kang polymerization process, maemo a karabelo, sebopeho sa reactant le li-additives li ama ts'ebetso ea eona joang.

Polyvinyl chloride resin: ho shebisisa hantle
Resin ea PVC e entsoe ka polymerizing vinyl chloride monomer, ts'ebetso e etsang liketane tse telele tsa likarolo tsa sebopeho CH2-CHCl. Tekanyo ea polymerization, hangata 590 ho 1500, e thusa ho eketsa matla le ho tšoarella ha thepa.

Likopo lefapheng la bongaka
Resin ea PVC e sebelisoa haholo indastering ea bongaka ka lebaka la thepa ea eona e ntle haholo. E atisa ho sebelisoa ho hlahisa lisebelisoa tsa bongaka tse kang li-tubing tse kenang methapong, mekotla ea mali, li-catheters le li-gloves tsa ho buoa. Ho tenyetseha ha PVC resin, ho hlaka, le khanyetso ea lik'hemik'hale li etsa hore e be e loketseng lits'ebetso tsa bongaka.

Lintlha tse amang ts'ebetso ea resin ea PVC
Ts'ebetso ea resin ea PVC e tla fapana ho latela lintlha tse fapaneng. Ts'ebetso ea polymerization e bapala karolo ea bohlokoa ho khetholla boima ba limolek'hule le tekanyo ea polymerization. Maemo a ho itšoara, a kang mocheso le khatello, le tsona li ama thepa ea sehlahisoa sa ho qetela. Ntle le moo, sebopeho sa li-reactants le ho eketsoa ha li-additives li ka fetola thepa ea resin ho fihlela litlhoko tse khethehileng tsa bongaka.

Li-additives ka resin ea PVC
Hangata li-additives li kenngoa ho resin ea PVC ho ntlafatsa thepa e khethehileng. Ka mohlala, li-plasticizers li ka eketsa ho feto-fetoha ha maemo, ho etsa hore thepa e tšoanelehe haholoanyane bakeng sa likopo tse hlokang ho sisinyeha le ho khumama. Ho eketsa li-stabilizers ho ka ntlafatsa ho hanyetsa mocheso le ho hanyetsa khanya ha resin le ho netefatsa bophelo ba eona ba tšebeletso. Li-additives tse ling li kenyelletsa li-modifiers, lubricant le li-filler, tseo kaofela li thusang ho ntlafatsa ts'ebetso le ts'ebeliso.

ha re phethela:
Polyvinyl chloride resin, kapa PVC resin, e ntse e tsoela pele ho ba motsoako oa bohlokoa indastering ea bongaka. Ho feto-fetoha ha eona, matla le ho hanyetsa lik'hemik'hale ho etsa hore e be thepa ea khetho bakeng sa lisebelisoa tsa bongaka. Ho utloisisa tšusumetso ea lintlha tse kang ts'ebetso ea polymerization, maemo a karabelo, sebopeho sa reactant le li-additives ho bohlokoa ho hlahisa li-resin tsa PVC tse nang le thepa e lakatsehang. Ha thekenoloji e ntse e tsoela pele, tsoelo-pele e eketsehileng ea resin ea PVC ha ho pelaelo hore e tla theha bokamoso ba mekhoa e mecha ea bongaka, e qetellang e ruisa bakuli le bafani ba tlhokomelo ea bophelo molemo.
