Ibibazo umunani ugomba kwitondera mugihe inshinge zibumbira mu icupa rya PET

1. Kuvura plastike

Kuberako PET macromolecules irimo amatsinda ya lipide kandi ifite imiterere ya hydrophilique, ingano zumva amazi kubushyuhe bwinshi.Iyo ibirimo amazi arenze imipaka, uburemere bwa PET buragabanuka mugutunganya, nibicuruzwa bigahinduka ibara kandi byoroshye.
Kubwibyo, mbere yo gutunganya, ibikoresho bigomba gukama, hamwe nubushyuhe bwa 150 ℃, amasaha arenga 4;muri rusange 170 ℃, amasaha 3-4.Uburyo bwo mu kirere burashobora gukoreshwa mugupima neza.Umubare wibicupa bya PET icupa ryibicuruzwa bitagomba gukoreshwa muri rusange ntibigomba kurenga 25%, kandi ibikoresho bitunganyirizwa bigomba gukama neza.

2. Guhitamo imashini ibumba inshinge

Kuberako PET ifite igihe gito gihamye nyuma yo gushonga hamwe no gushonga hejuru, birakenewe guhitamo sisitemu yo gutera inshinge hamwe nibice byinshi bigenzura ubushyuhe hamwe no kutishishanya no kubyara ubushyuhe mugihe cya plastiki, hamwe nuburemere nyabwo bwibicuruzwa (harimo ibikoresho byo gufata amazi) ntibigomba kuba munsi ya 2/3 byinshinge yimashini.

3. Kubumba no gusuka igishushanyo mbonera

PET icupa rya urusoro, mubisanzwe byakozwe numuyoboro wubushyuhe wububiko, imashini yerekana imashini yerekana imashini hagati yicyiza cyo kugira isahani yubushyuhe, ubunini bwayo bugera kuri 12mm, kandi isahani yubushyuhe igomba kuba ishobora kwihanganira umuvuduko mwinshi.Umunaniro ugomba kuba uhagije kugirango wirinde ubushyuhe bwaho cyangwa gucikamo ibice, ariko ubujyakuzimu bwicyambu gisohoka ntabwo burenga 0.03mm, naho ubundi biroroshye kubyara uruhande ruguruka.

4. Gushonga ubushyuhe

Uburyo bwo gupima uburyo bwo guhumeka ikirere, 270-295 ℃ urwego, urwego rwongerewe GF-PET rushobora gushyirwaho 290-315 ℃, nibindi.

5. Umuvuduko wo gutera inshinge

Umuvuduko rusange wo gutera inshinge ugomba kwihuta kugirango wirinde kwandura imburagihe mugihe cyo gutera inshinge.Ariko byihuse cyane, igipimo cyogosha ni kinini, kora ibikoresho byoroshye.Kurasa mubisanzwe birangira mumasegonda 4.

6. Umuvuduko winyuma

Hasi nibyiza, kugirango wirinde kwambara.Mubisanzwe ntibirenza 100bar, mubisanzwe ntibikoreshwa.

7. Igihe cyo kuguma

Ntugakoreshe umwanya muremure kugirango wirinde kugabanuka kwa molekile, kandi ugerageze kwirinda ubushyuhe buri hejuru ya 300 ℃.Niba guhagarika bitarenze iminota 15, kora gusa kuvura ikirere;niba iminota irenze 15, hanyuma usukure hamwe na viscosity PE, hanyuma ugabanye ubushyuhe bwa silinderi kubushyuhe bwa PE, kugeza utangiye.

8. Kwirinda

Gusubiramo ibikoresho ntibishobora kuba binini cyane, bitabaye ibyo, byoroshye kubyara umusaruro "ikiraro" kandi bigira ingaruka kuri plastike;
Niba kugenzura ubushyuhe bwububiko atari byiza, cyangwa kugenzura ubushyuhe bwibintu ntibikwiye, byoroshye kubyara "igihu cyera" na opaque;ubushyuhe bwubushyuhe buri hasi kandi buringaniye, umuvuduko ukonje byihuse, kristu nkeya, noneho ibicuruzwa biragaragara.

Huangyan Leiao Molding Co., Ltd iherereye mu mujyi wa Huangyan umujyi wubatswe, Taizhou, intara ya Taizhou, akaba ari “umujyi wavukiye mu Bushinwa”.Isosiyete ikora cyane cyane mu gukora inshinge zatewe inshinge, ifite uburambe bwimyaka myinshi, cyane cyane mu gukora no gutunganya ibicuruzwa biva mu icupa, ibicuruzwa bya PET, ibicuruzwa biva mu icupa, imodoka imbere n’imbere yo gushushanya…… Mu nshinge za valve inshinge zishyushye ziruka sisitemu yububiko ifite tekinoroji yihariye yo gutunganya no gutunganya, ishingiye ku gitekerezo cya "Imicungire y’ubunyangamugayo", hamwe n’abakiriya bo mu gihugu ndetse n’amahanga kugira ngo bashireho umubano mwiza w’ubufatanye mu gihe kirekire, ndizera ko Leiao izakubera ikizere muri koperative. uruganda.
