Nhanganyaya: Patinotora bhodhoro reshampoo rinojairika, pachava nechiratidzo chePET pasi pebhodhoro, zvinoreva kuti chigadzirwa ichi ibhodhoro rePET. Mabhodhoro ePET anonyanya kushandiswa muindasitiri yekuwachisa nekuchengetedza uye ane huwandu hwakawanda. Muchinyorwa chino, tinonyanya kutaura nezvebhodhoro rePET sechirongo chepurasitiki.
Mabhodhoro ePET midziyo yepurasitiki yakagadzirwa nePETzvinhu zvepurasitikikuburikidza nekugadzirisa nhanho imwe chete kana mbiri. PET purasitiki ine hunhu hwehuremu hushoma, kujeka kwakanyanya, kuramba kukanganiswa uye hazvisi nyore kupwanya.
Maitiro ekugadzira
1. Nzwisisa preform
Chigadzirwa che preform chinogadzirwa nejekiseni. Sechigadzirwa chepakati chakapedzwa chekushandisa biaxial stretch blow molding, bhotoro re preform rakapedzwa panguva yekuumbwa kwejekiseni, uye saizi yaro haizoshanduke panguva yekupisa nekutambanudza/kuputira. Saizi, huremu, uye ukobvu hwemadziro e preform ndizvo zvinhu zvatinofanira kunyatsoteerera patinoputira mabhodhoro.
A. Maumbirwo emudumbu mubhodhoro
B. Kuumbwa kwemudumbu mubhodhoro
2. Kuumba mabhodhoro ePET
Nzira yedanho rimwe chete
Maitiro ekupedzisa kubaya, kutambanudza nekufuridza mumuchina mumwe chete anonzi nzira yedanho rimwe chete. Nzira yedanho rimwe chete ndeyekuita kutambanudza nekufuridza mushure mekunge preform yatonhodzwa mushure mekuumba jekiseni. Zvakanakira zvikuru ndezvekuchengetedza simba, kushanda zvakanyanya, kusashanda nemaoko uye kusvibiswa kushoma.
Nzira ine nhanho mbiri
Nzira iyi ine matanho maviri inoparadzanisa injection nekutambanudza nekuputira, uye inozviita pamichina miviri panguva dzakasiyana, inozivikanwawo se injection stretching nekuputira. Danho rekutanga nderekushandisa injection molding muchina kubaya preform. Danho rechipiri nderekudziisa zvakare temperature yemumba preform nekuitambanudza nekuiputira mubhodhoro. Kubatsira kwenzira iyi ine matanho maviri nderekutenga preform yekuputira. Inogona kuderedza mari (tarenda nemidziyo). Vhoriyamu yepreform idiki zvikuru pane yebhodhoro, iyo iri nyore kutakurwa nekuchengetwa. Preform inogadzirwa munguva yekunze kwemwaka inogona kuputirwa mubhodhoro munguva yekupisa.
3. Maitiro ekuumba mabhodhoro ePET
1. Zvinhu zvePET:
PET, polyethylene terephthalate, inonzi polyester. Zita rechirungu ndiPolyethylene Terephthalate, iyo inogadzirwa nepolymerization reaction (condensation) yezvinhu zviviri zvemakemikari: terephthalic acid PTA (terephthalic acid) uye ethylene glycol EG (ethylicglycol).
2. Ruzivo rwakawanda nezve bhodhoro remuromo
Muromo webhodhoro une dhayamita ye Ф18, Ф20, Ф22, Ф24, Ф28, Ф33 (inoenderana nehukuru hwemuromo webhodhoro), uye tambo dzinogona kukamurwa kuita: 400, 410, 415 (inoenderana nehuwandu hwekutenderera kweshinda). Kazhinji, 400 inotenderera shinda imwe chete, 410 inotenderera shinda imwe nehafu, uye 415 inotenderera shinda mbiri dzakakwirira.
3. Muviri webhodhoro
Mabhodhoro ePP nePE anowanzova nemavara akasimba, PETG, PET, PVC anowanzova akajeka, kana kuti ane ruvara uye akajeka, ane pfungwa yekupenya, uye mavara akasimba haawanzo shandiswa. Mabhodhoro ePET anogonawo kupfapfaidzwa. Pane nzvimbo yakatetepa pasi pebhodhoro rakaumbwa. Rinopenya pasi pechiedza. Pane tambo yekubatanidza pasi pebhodhoro rakaiswa.
4. Kufananidza
Zvigadzirwa zvikuru zvinofananidza mabhodhoro emvura inoputika ipurasitiki yemukati (inowanzo shandiswa pazvinhu zvePP nePE), macap ekunze (anowanzo shandiswa paPP, ABS neacrylic, zvakare akagadzirwa nemagetsi, uye aruminiyamu yakagadzirwa nemagetsi, inonyanya kushandiswa pakuisa spray toner), chifukidziro chemusoro wepombi (chinowanzo shandiswa pakugadzira essence nelotion), macap anoyangarara, macap anoyangarara (macap anoyangarara uye macap anoyangarara anonyanya kushandiswa pakugadzira makemikari ezuva nezuva ane ropa rakawanda), nezvimwewo.
Kushandiswa
Mabhodhoro ePET anoshandiswa zvakanyanya muindasitiri yezvizoro,
kunyanya muindasitiri yekuwacha nekutarisira,
kusanganisira shampoo, mabhodhoro eshawa, toner, mabhodhoro ekubvisa makeup, nezvimwewo.
zvese zvaputika.
Kufunga nezvekutenga
1. PET inongova imwe yezvinhu zviripo zvemabhodhoro ekubvisa mabhodhoro. Kunewo mabhodhoro ekubvisa mabhodhoro ePE (akapfava, mavara akasimba, kugadzira kamwe chete), mabhodhoro ePP (akaoma, mavara akasimba, kugadzira kamwe chete), mabhodhoro ePETG (akajeka kupfuura PET, asi asingawanzo shandiswa muChina, anodhura zvakanyanya, marara akawanda, kugadzira kamwe chete, zvinhu zvisingadzokororwe), mabhodhoro ePVC (akaoma, asingakuvadzi nharaunda, asingaonekwe zvakanyanya kupfuura PET, asi akajeka kupfuura PP nePE)
2. Midziyo ine nhanho imwe chete inodhura, michina ine nhanho mbiri yakachipa
3. Zviumbwa zvemabhodhoro ePET zvakachipa.
