Bhodhoro rePET reshampoo

2026-01-30

Patinotora bhodhoro reshampoo rinowanzoshandiswa, pachava nepepa rePET pasi pebhodhoro, zvichiratidza kuti chigadzirwa ichi ibhodhoro rePET. Mabhodhoro ePET anonyanya kushandiswa muindasitiri yezvekuchengetedza vanhu uye akawanda acho ane huwandu hwakakura. Mabhodhoro ePET midziyo yepurasitiki inowanikwa nekugadzira zvinhu zvepurasitiki zvePET nenzira imwe chete kana mbiri. Plastiki yePET ine hunhu hwekureruka, kujeka zvakanyanya, uye kuramba kupwanyika kana kuputsika.

PET, kana kuti polyethylene terephthalate, inozivikanwawo se polyester. Zita rayo rechirungu ndiPolyethylene Terephthalate, iyo inogadzirwa ne polymerization reaction (condensation) yezvinhu zviviri zvemakemikari: terephthalic acid (PTA) uye ethylene glycol (EG). Preforms zvinhu zvakagadzirwa ne injection-molded. Sechinhu chepakati chakapedzwa chekutambanudza biaxial uye blow molding, mutsipa we preform unoumbwa panguva ye injection molding stage, uye saizi yawo haizoshanduke panguva yekupisa uye kutambanudza/kuputira blow molding. Saizi, huremu, uye ukobvu hwemadziro e preform zvinhu zvinofanirwa kutariswa zvakanyanya panguva ye blow molding process yebhodhoro.

Pakugadzirira mabhodhoro akaumbwa nemhepo, maPET chips anotanga apinzwa mu preform. Zvinodiwa kuti chikamu chezvinhu zvakadzokororwa chisanyanya kukwira (pasi pe5%), uye nguva dzekudzokorodza hadzifanirwe kudarika mbiri. Kurema kwemamorekuru nekusimba hazvifanirwe kunge zvakaderera zvakanyanya (huremu hwemamorekuru 31,000 - 50,000, kusimba kwemukati 0.78 - 0.85 cm³/g). Zvinoenderana neNational Food Safety Law, zvinhu zvakadzokororwa hazvibvumidzwe kushandiswa pakurongedza chikafu nemishonga. Ma preform akaumbwa nejekiseni anofanira kuchengetwa kwemaawa anopfuura makumi maviri nemana asati ashandiswa. Ma preform asina kushandiswa mushure mekudziya anofanira kuchengetwa kwemaawa anopfuura makumi mana nemasere asati adziiswazve. Nguva yekuchengetedza yemabhodhoro haifanirwe kudarika mwedzi mitanhatu. Hunhu hwe preform hunonyanya kuenderana nehunhu hwezvinhu zvePET, saka zvakakosha kusarudza zvinhu zviri nyore kuputira nekuumba, uye kugadzira maitiro ekuumba e preform akakodzera. Ongororo dzinoratidza kuti ma preform akagadzirwa nezvinhu zvakatorwa kunze kwenyika zvine viscosity yakafanana zviri nyore kuputira mold pane akagadzirwa nezvinhu zvakabikwa zvemumba. Zvisinei, kune boka rimwe chete re preforms, mazuva akasiyana ekugadzira anogona kuda maitiro akasiyana e blow molding. Hunhu hwe preform hunosarudza kuoma kwe blow molding process. Zvinodiwa zve preform kuchena, kujeka, kusasviba, kusachena, kusachena, kureba kwakakodzera kwe injection point, uye halo yakaipoteredza.

Mabhodhoro ePP nePE anowanzova nemavara akajeka, nepo PETG, PET, nePVC anowanzova akajeka kana kuti ane mavara akajeka uye anopenya, uye mavara akajeka haawanzo shandiswa. Mabhodhoro ePET anogonawo kupendwa nespray. Pane nzvimbo yakapfava pasi pebhodhoro rakaumbwa, iro rinopenya pasi pechiedza. Pasi pebhodhoro rakaumbwa ne injection-blow rine tambo yekubatanidza. Zvishongedzo zvikuru zvemabhodhoro akaumbwa zvinosanganisira zvinovhara mukati (zvinowanzo shandiswa paPP nePE), macap ekunze (anowanzo shandiswa paPP, ABS, uye acrylic, uye anowanikwawo muma electroplated, electro-galvanized, uye spray-painted finishes, anowanzo shandiswa pamabhodhoro etoner), ma pump head cover (anowanzo shandiswa pa essence ne lotion), ma flip caps, uye snap caps (anonyanya kushandiswa mu large circulation daily chemical lines).
