Mapoinzi ekutarisisa muPVC jekiseni molding process

PVC chinhu chinonzwa kupisa, uye maitiro ayo ekuumba jekiseni haana kunaka.Chikonzero ndechekuti yakanyanya kunyunguduka tembiricha kana yakawandisa kupisa nguva inogona kuora nyore PVC.Naizvozvo, kudzora tembiricha yekunyungudika ndiyo kiyi yekujekiseni kuumba PVC zvigadzirwa.Iyo inopisa sosi yekunyungudutsa PVC mbishi zvinhu inobva kune maviri maficha, anoti, shear kupisa kwepurasitiki inogadzirwa nescrew motion uye inodzivirira waya yekudziya yekunze kwemadziro ebhari, iyo inonyanya kupisa kupisa kwescrew motion.Kupisa kwekunze kwebhodhoro ndiko kunyanya kupisa kunopihwa kana muchina watanga.

PVC yaimbove yakakura pasi rose-chinangwa chepurasitiki ine huwandu hwakawanda hwekushandisa, kunyanyaPVC pombi uye fittings.

Aya mapoinzi anotevera anozocherechedzwa mukugadzirwa kwechigadzirwa uye mold dhizaini:

1. Chigadzirwa chacho hachifaniri kuva nemakona akapinza kana kuchinja kwekukurumidza sezvinobvira, uye kukora hakuzoshanduki zvakanyanya kudzivirira kuparara kwePVC.

2. Iyo mold ichave iine dhizaini angle yeanopfuura madhigirii gumi, uye shrinkage inenge 0.5% ichachengetwa.

3. Mapoinzi akati wandei anofanirwa kutariswa mune dhizaini yekuyerera chiteshi che mold

A. Chiteshi chejekiseni che mold chichava chihombe zvishoma kudarika buri remuromo uye chihombe kudarika dhayamita yemharadzano yemugero mukuru wekuyerera, kuitira kuti zvinhu zvePVC zvirege kuyerera mumhango ye mold uye kudzvanywa kunogona kuenzana.

B. Kucheka gedhi kuchashandiswa zvakanyanya sezvinobvira kudzivirira slag yakanyunguduka kubva mukuyerera ichienda muchigadzirwa uye tembiricha yemumhanyi kubva pakuderera uye kuita kuti zvive nyore kuumba.

C. Gedhi richagadzirwa pamadziro akakora echigadzirwa ane upamhi hwakakwana uye kureba kwe6-8mm kuita kuti zvinhu zvePVC zvifambe zvakanaka.

D. Kuti utsigire kudonhedzwa kwekumanikidza uye nyore dhizaini, chiteshi chekuyerera chinofanira kunge chakatenderera, uye dhayamita inofanira kuva 6-10mm zvichienderana nekukura kwechigadzirwa uye uremu.

4. Iyo tembiricha yekuumbwa ichave yakashongedzerwa nekutonhodza mvura yekudzora mudziyo kuita kuti mold tembiricha inodzoreka pakati pe30 ℃ uye 60 ℃.

5. Kumusoro kwechiumbwa kuchave kwakatsetseka uye kwakachena, uye chrome plating ichashandiswa kudzivirira kuora.
