PVC ka terata le ka thapo: Thepa ea thepa e bohlokoa

1.PVC Resin

PVC resin ke linear thermoplastic polymer e entsoeng ke polymerization ea vinyl chloride monomers. Sebopeho sa eona sa molek'hule se na le:

(1) Joaloka polymer ea thermoplastic, e bonts'a polasetiki e ntle le ho fetoha habonolo.

(2) Ho ba teng ha C-Cl polar bonds ho fana ka polarity e matla ea resin, e leng se etsang hore ho be le boemo bo phahameng ba dielectric (ε) le dissipation factor (tanδ), ha e ntse e fana ka matla a phahameng a dielectric ka maqhubu a tlaase. Litlamo tsena tsa polar li boetse li kenya letsoho ho matla a matla a intermolecular le matla a phahameng a mechine.

(3) Liathomo tsa chlorine mohahong oa limolek'hule li fana ka thepa e thibelang malakabe hammoho le lik'hemik'hale tse ntle le boemo ba leholimo. Leha ho le joalo, liathomo tsena tsa chlorine li senya sebopeho sa kristale, e leng se lebisang ho hanyetsa mocheso o batlang o le tlase le ho hanyetsa serame, ho ka ntlafatsoang ka li-additives tse nepahetseng.

2.Mefuta ea PVC Resin

Mekhoa ea ho etsa polymerization bakeng sa PVC e kenyelletsa: polymerization ea ho emisa, polymerization ea emulsion, polymerization ea bongata, le polymerization ea tharollo.

Mokhoa oa ho emisa polymerization hajoale o ntse o le teng haholo tlhahisong ea resin ea PVC, 'me ona ke mofuta o sebelisoang lits'ebetsong tsa terata le likhoele.

Li-resin tsa PVC tse emisitsoeng-polymerized li arotsoe ka mefuta e 'meli ea meralo:
Resin ea mofuta o hlephileng (mofuta oa XS): E khetholloa ka sebopeho sa porous, ho monngoa ha polasetiki e phahameng, ho plastara habonolo, taolo e bonolo ea ho sebetsa, le likaroloana tse seng kae tsa li-gel, e leng se etsang hore e be khetho e ratoang bakeng sa lisebelisoa tsa terata le cable.
Resin ea mofuta oa Compact (mofuta oa XJ): E sebelisoa haholo bakeng sa lihlahisoa tse ling tsa polasetiki.

3.Lintho tsa bohlokoa tsa PVC

(1) Thepa ea Motlakase oa Motlakase: Joaloka lisebelisoa tsa dielectric tse phahameng haholo, PVC resin e bonts'a thepa e ntle ea motlakase empa e tlaase hanyenyane ha e bapisoa le lisebelisoa tse seng tsa polar tse kang polyethylene (PE) le polypropylene (PP). Bolumo bo hanyetsanang bo feta 10¹⁵ Ω·cm; ka 25 ° C le 50Hz khafetsa, kamehla dielectric (ε) e tloha ho 3.4 ho ea ho 3.6, e fapaneng haholo le mocheso le liphetoho tsa maqhubu; The dissipation factor (tanδ) e tloha ho 0.006 ho isa ho 0.2. Matla a ho senya a lula a le holimo mocheso oa kamore le maqhubu a matla, a sa amehe ke polarity. Leha ho le joalo, ka lebaka la tahlehelo ea eona e batlang e le ngata ea dielectric, PVC ha e tšoanelehe bakeng sa lisebelisoa tse phahameng tsa motlakase le tsa maqhubu a phahameng, hangata e sebelisoa e le lisebelisoa tsa ho pata bakeng sa likhoele tse tlaase le tse mahareng tse tlase ho 15kV.

(2) Botsofali Botsitso: Le hoja sebopeho sa limolek'hule se fana ka maikutlo a botsitso bo botle ba botsofali ka lebaka la litlamo tsa chlorine-carbon, PVC e atisa ho lokolla hydrogen chloride nakong ea ts'ebetso tlas'a khatello ea mocheso le mochine. Oxidation e lebisa ho senyeha kapa ho hokahanya, ho bakang ho fifala, ho putlama, ho fokotseha ho hoholo ha thepa ea mochini, le ho senyeha ha ts'ebetso ea ho kenya motlakase. Ka hona, li-stabilizers tse nepahetseng li tlameha ho eketsoa ho ntlafatsa ho hanyetsa botsofali.

(3) Thermomechanical Properties: Joaloka polymer ea amorphous, PVC e teng libakeng tse tharo tsa 'mele ka mocheso o fapaneng: boemo ba khalase, boemo bo phahameng ba elastic, le boemo ba ho phalla ha viscous. Ka mocheso oa khalase (Tg) o pota-potileng 80 ° C le mocheso o phallang o ka bang 160 ° C, PVC e boemong ba eona ba khalase mocheso oa kamore e ke ke ea finyella litlhoko tsa kopo ea mohala le mohala. Phetoho ea hlokahala ho fihlela elasticity e phahameng mocheso oa kamore ha o ntse o boloka mocheso o lekaneng le ho hanyetsa serame. Ho eketsoa ha li-plasticizers ho ka fetola mocheso oa phetoho ea khalase ka katleho.

AboutLEFATŠE LE LE MONG (OW Cable)

Joaloka morekisi ea ka sehloohong oa thepa e tala ea terata le lithapo, ONE WORLD (OW Cable) e fana ka metsoako ea boleng bo holimo ea PVC bakeng sa ho kenya letsoho le lisebelisoa tsa sheathing, tse sebelisoang haholo ho lithapo tsa motlakase, lithapo tsa mohaho, lithapo tsa puisano le lithapo tsa likoloi. Lisebelisoa tsa rona tsa PVC li na le lisebelisoa tse ntle tsa motlakase, ho lieha ha lelakabe, le ho hanyetsa boemo ba leholimo, ho lumellana le litekanyetso tsa machaba tse kang UL, RoHS, le ISO 9001. Re ikemiselitse ho fana ka tharollo ea PVC e tšepahalang le e theko e tlaase e lumellanang le litlhoko tsa bareki ba rona.
