Lintlha tse ling mabapi le chlorinated polyethylene:

Chlorinated polyethylene (CPE) ke ntho e entsoeng ka polymer e nang le ponahalo ea phofo e tšoeu, e se nang chefo ebile ha e na monko. E na le khanyetso e ntle ea boemo ba leholimo, khanyetso ea ozone, k'hemik'hale e hanyetsanang le botsofali, hammoho le khanyetso e ntle ea oli, ho lieha ha lelakabe, le thepa ea mebala. Matla a matle (a ntse a tenyetseha ho -30 ℃), tšebelisano e ntle le lisebelisoa tse ling tsa polymer, mocheso o phahameng oa ho bola, ho bola ho hlahisa HCL, e ka susumetsang karabelo ea dechlorination ea CPE.

Mokhoa oa metsi oa chlorinated polyethylene o sebelisoa hangata, o nang le litšenyehelo tse tlase tsa tlhahiso le tšilafalo e mpe. Mokhoa o mong ke oa ho fanyeha, o seng o hōlile. Ba malapeng ba ka ba le nts'etsopele ea bobeli le ts'ebeliso ka nts'etsopele e potlakileng, 'me lebelo la ho omisa le potlakile. E atisa ho sebelisoa litanka tsa polokelo le mehaho ea tšepe ho ntlafatsa polokeho ea kaho.

Meetso ea lapeng e nang le chlorinated polyethylene (CPE) hangata e khetholloa ka linomoro tse kang 135A, 140B, joalo-joalo. Linomoro tsa pele 1 le 2 li emela "residual crystallinity" (TAC value), 1 e emela boleng ba TAC pakeng tsa 0 le 10%, 2 e emela TAC. boleng> 10%, palo ea bobeli le ea boraro e emela litaba tsa chlorine, mohlala, 35 e emela litaba tsa chlorine tsa 35%, 'me nomoro ea ho qetela ke lengolo la ABC, le sebelisetsoang ho bontša boima ba limolek'hule tsa PE e tala. A ke e kholo ka ho fetisisa 'me C ke e nyenyane ka ho fetisisa.

Tšusumetso ea boima ba molek'hule: Chlorinated polyethylene (CPE) e na le boima bo phahameng ka ho fetisisa ba molek'hule le viscosity e phahameng ea ho qhibiliha linthong tsa eona tsa mofuta oa A. Viscosity ea eona e lumellana hantle le PVC 'me e na le phello e ntle ka ho fetisisa ea ho hasana ho PVC, e etsa marang-rang a nepahetseng joaloka mokhoa oa ho hasana. Ka hona, thepa ea mofuta oa A ea CPE hangata e khethoa e le phetoho bakeng sa PVC.

Haholo-holo e sebelisetsoang: terata le thapo (lithapo tsa morafo oa mashala, lithapo tse boletsoeng ka litekanyetso tsa UL le VDE), hose ea hydraulic, hose ea koloi, tepi, poleiti ea rabara, phetoho ea pipe ea profil ea PVC, lisebelisoa tsa makenete, phetoho ea ABS, joalo-joalo. Haholo-holo nts'etsopele ea indasteri ea terata le lithapo le indasteri ea tlhahiso ea likarolo tsa likoloi e tsamaisitse tlhokahalo ea tšebeliso ea rabara e thehiloeng ho CPE. Rubber based CPE ke rabara e khethehileng ea maiketsetso e nang le ts'ebetso e phethahetseng e felletseng, e hanyetsanang le mocheso oksijene le botsofali ba ozone, le ho lieha ho hoholo ha lelakabe.

Lintlha tse amang mocheso oa ho bola oa mocheso oa CPE

Thepa ea CPE ka boeona e amana le litaba tsa eona tsa chlorine. Haeba litaba tsa chlorine li phahame, ho bonolo ho bola;

E amana le bohloeki. Ho tlosoa ho sa lekaneng ha li-initiators, li-catalysts, acids, bases, joalo-joalo tse kenyelletsoeng nakong ea ts'ebetso ea polymerization, kapa ho kenngoa ha metsi nakong ea polokelo le lipalangoang, ho ka fokotsa botsitso ba polymer. Lintho tsena li ka baka karabelo ea ho senyeha ha limolek'hule, 'me CPE e na le lintho tse ngata tse tlase tsa boima ba limolek'hule tse kang Cl2 le HCl, tse ka potlakisang ho bola ha mocheso oa resin;
