kopo

Mokhoa oa ho etsa li-hose tsa PVC:

Ho kopanya → ho duba → granulation ea extrusion → sebopeho sa extrusion → ho khoasolla → ho khoaela → sephuthelo → tlhahlobo ea boleng → sehlahisoa se felileng

1. Ho luba ha metsoako

Mefuta eohle ea lihlahisoa tse tala e lekanngoa ka nepo ebe e kenngoa ka har'a kneader ka tatellano e itseng.Tatelano ea ho fepa: PVC resin, plasticizer, stabilizer, lubricant.Ha mocheso o fihla ho 100 ~ 110 ℃, thepa e ka lokolloa.

2.extrusion granulation

Tshebetso ena ho laola mocheso, ntlha e phahameng ka ho fetisisa ea mocheso oa thepa e lokela ho laoloa ka holimo ho feta mocheso o qhibilihang oa thepa, o ka tlaase ho feta mocheso oa extrusion oa ho bōpa, ke hore, pakeng tsa 155 ~ 160 ℃.Granulation e lokela ho finyella sepheo sa ho kopanya ka ho feletseng le polasetiki ea pele.

Thempereichara ea sebaka ka seng sa granulator ke ka tsela e latelang:

Sebaka sa 80 ~ 90 ℃;Sebaka sa 130 ~ 140 ℃;Libaka tse tharo 140 ~ 150 ℃;Ho tloha 150 ~ 160 ℃.

3. extrusion tube ho theha

Mocheso oa ho etsa li-tube tsa extrusion o phahame hanyane.Ka kakaretso, pepeneneng ea pipe e amana le mocheso oa ho theha.Mocheng o itseng oa mocheso, ponahalo ea mocheso o phahameng e ntle, 'me ka tsela e fapaneng.Ka nako e ts'oanang, lebelo la ho hula le lebelo la ho pholisa le tla ama ho pepeseha ha phala.Lebelo la ho hula le leholo hanyenyane, lebelo la ho pholisa le potlakile, 'me ho pepeseha ha phala ho molemo.Lebelo la ho hula hangata ke 10% ~ 15% ka potlako ho feta lebelo la extrusion.Pholiso ea hose e bonaletsang e fafatsoa ka metsi a batang ha ho shoa nko ebe e pholile ka tanka ea metsi.

Mocheso oa sebaka se seng le se seng sa ho bopa extrusion ke ka tsela e latelang:

Sebaka sa 1:90 ℃;Sebaka sa bobeli 140 likhato 5 ℃;Libaka tse tharo 160 likhato 5 ℃;Libaka tse 'nè 170 likhato 5 ℃.

4. Litlhokomeliso tsa hose extrusion ea PVC:

1. ka ho toba ka popo ea extrusion ea phofo, mocheso oa extruder o ka tlase ho 5 ℃ ho feta ka thepa ea granular.

2. Ho phaella ho bophara bo bonyenyane (φ60mm ka tlase) ba tube e pholileng e se nang letho ha e hloke hore e phatloe moeeng o hatelitsoeng, bophara bo boholoanyane ba tube e se nang letho e pholileng e tlameha ho phunyeletsoa moeeng o hatelitsoeng oa tube, e le ho etsa bonnete ba hore ho nepahala le botsitso ba boholo ba bophara ba tube.Ela hloko khatello e tsitsitseng ea moea o hatelitsoeng.

3. Ela hloko botsitso ba lebelo la ho hula 'me u qobe phetoho ea bophara ba phala kapa botenya ba lebota bo bakoang ke ho se tsitse ha ho hula.

4. Haeba mochine o koetsoe ka nako e telele, o tlameha ho qhaqhoa le ho hloekisoa ho qoba mathata a ho bola.
