Jekiseni kuumba maitiro ePVC zvinhu

PVC zvinhu hazvidhure, zvakasikwa anti-kuzvimba, yakaoma uye yakasimba, yakanaka makemikari kuramba, shrinkage mwero we0.2-0.6%, zvigadzirwa zviri kuwedzera kushandiswa mumidziyo yemagetsi, michina, kuvaka, zvinodiwa zvezuva nezuva, matoyi, kurongedza, kune maitiro emagetsi. PVC zvinhu, kuongororwa kwechigadzirwa jekiseni kuumba maitiro ndeaya anotevera:

一、Zvinhu zvePVC zvinhu

PVC kupisa kugadzikana kwakashata, kuumba tembiricha uye kuparara tembiricha iri pedyo, kusafamba zvakanaka, kutaridzika nyore kuumba urema hwakaipa, PVC zvinhu kupisa kusagadzikana hakuna kunaka, yakanyanya nyore kupisa, acidic gasi uye ngura yeforoma, kugadzirisa. inogona kuwedzera plasticizer kuti iwedzere fluidity yayo, - kazhinji inofanira kuwedzera zvinowedzera kushandisa, simba rayo, magetsi ekudzivirira, zvakanaka makemikari kuramba.

二、Mold uye gedhi dhizaini

Kuti upfupise kutenderera kwejekiseni, iyo ipfupi chiteshi chejekiseni zviri nani, chikamu chemuchinjiko chinofanirwa kunge chakaita sebindu, dhayamita shoma yejekiseni chiteshi ndeye 6 mm, mugadheni koni, kona yemukati ye5 madhigirii, zviri nani. nematsime anotonhora, matsime anotonhora anogona kudzivirira zvisina kunyungudutswa semi-yakasimba zvinhu mugomba, uye zvinhu izvi zvinokanganisa kupedzisa kwepamusoro uye kusimba kwechigadzirwa.

Kufa kunofanirwa kunge kuri pakati pe0.50 ne10 kuti ive nechokwadi chekuti gonhi rine midziyo yekufemesa yakakwana.Iyo yakajairwa buri gomba saizi ndeye 0.03-0.05mm kudzika uye 6mm yakafara, kana 0.03-0.05mm clearance kutenderedza pini yega yega ejector.Iyo dhifi inofanirwa kugadzirwa nesimbi isina tsvina kana yakaoma chrome yakaiswa mukati.

三、PVC molding process

PVC ipurasitiki inodzivirira kupisa.Kupisa kana kuveura kwakanyanya kunokonzera kuora uye kupararira nokukurumidza, nokuti chimwe chezvigadzirwa zvekuora (zvakadai seasidhi kana HCI) zvichava nemigumisiro inobatsira, zvichiita kuti iwedzere kuparara kwemaitiro, uye asidi inoparadza simbi uye iite kuti ichinje.Kana iyo yakasvibiswa, iyo inodzivirira yesimbi inoputika, inokonzera ngura, iyo inonyanya kukuvadza muviri wemunhu.Iyo yakajairwa screw kureba-dhayamita reshiyo ndeye 18~24: 1, iyo-nhanho-nhatu reshiyo ndeye 3:5:2, uye compression reshiyo i1.8~2.Kudzika kwescrew groove muchikamu chekudya kunokurudzirwa sezvinotevera:

Kumhanya kwejekiseni kunofanirwa kunonoka, zvikasadaro kuveura kwakanyanya kunosvibisa zvinhu.Paunenge uchishandisa UPVC kugadzira zvigadzirwa zvakatsetseka zvakakora-madziro, kumhanya kwejekiseni remhando dzakawanda kunofanirwa kushandiswa.Kana mitsetse yebrown yakapenya ichipenya kubva kugedhi, zvinoreva kuti jekiseni rinomhanya zvakanyanyisa.quick.

Iyo muromo we screw inofanira kuva nekona yemukati ye 25 ~ 30 degrees.Kana sikuruu iri panzvimbo, chinhambwe chiri pakati pemuromo nemuromo chinofanira kuva 0.7 ~ 1.8mm.Iyo screw inofanira kugadzirwa nesimbi isina tsvina kana chrome-plated.

1)Screw gasket: Iyo screw gasket iri pakati pe2 ~ 3mm, uye iyo yakakura-chiyero mukana wakakura.

2)Injection vhoriyamu: Iyo chaiyo nguva yekugara haifanirwe kudarika 3 maminetsi.

3) Kuiswa tembiricha yebhare:

Iwo tembiricha akapihwa ndeekureva chete, uye kugadzirisa kwakakodzera kunoitwa zvinoenderana nemamiriro chaiwo emuchina uye mbishi zvinhu, izvo zvinogona zvakare kudarika inokurudzirwa siyana.

Tembiricha yepakati yekudyisa chikamu muchikamu chepamberi chevhu remuvhu (0C) 30-60 170-190 160-180 150-170

Iro jekiseni vhoriyamu rinoshandiswa 140-160 i20 ~ 85% ye theoretical jekiseni vhoriyamu yemuchina.Iyo idiki iyo jekiseni vhoriyamu yakanyatso shandiswa, inorebesa nguva yekuchengeta zvinhu uye inowedzera njodzi yekuipa mushure mekupisa.cin.com

4) Barrel yekugara nguva:

Pasi pekutonga kwekushisa kwe2000C (rubber material), nguva yakawanda yekugara kwebhodhoro inogona kudarika maminetsi mashanu, kana tembiricha iri 2100C.

5) jekiseni kumhanya:

Kumhanya kwejekiseni kunofanirwa kunonoka, zvikasadaro, zvinhu zvinodzikisira nekuda kwekuveura kwakanyanya.Multi-stage jekiseni kumhanya kunofanirwa kushandiswa kana uchishandisa UPVC kugadzira yakanyanya kutsetseka gobvu madziro zvigadzirwa.Kana paine mitsetse yebrown yakapenya inopenya kubva kugedhi, zvinoreva kuti jekiseni rinomhanya zvakanyanyisa.quick.
