Kugadziriswa kweTPU: Mhando Dzakajairika, Maitiro, uye Mashandisirwo
——Yakaunzwa naYantai Linghua New Material Co., Ltd.
Semugadziri wehunyanzvi akazvipira kutsvagurudza, kugadzira, uye kugadzira zvinhu zveTPU (Thermoplastic Polyurethane) zvinoshanda zvakanyanya, Yantai Linghua New Material Co., Ltd. inonzwisisa kuti kunyangwe TPU ichipa mashandiro akanaka kwazvo, inewo miganhu yayo yakadai sekusakwana kwekupisa, kutsva, uye kukwegura panguva yekushandiswa kwenguva refu panze. Kuti isangane nezvinodiwa zvemaindasitiri akasiyana-siyana, kugadzirisa kwakakosha kuti "iwedzere simba uye ikunde kusasimba."
Pazasi, tinotsanangura zvakarongeka mhando dzakajairika dzekuchinja kweTPU, maitiro akakosha, uye mashandisirwo adzo akajairika, tichiratidza kugona kwaLinghua mukupa mhinduro dzeTPU dzakagadzirirwa.
I. Mhando Dzakajairika dzeKugadziriswa kweTPU
Kugadziriswa kweTPU kwakakamurwa kuva kusanganiswa kwemuviri uye kugadziriswa kwemakemikari. Yekutanga yakaita se "kusanganisa saradhi," kusanganisa zvikamu zvakasiyana, nepo yekupedzisira yakafanana ne "kubika," kushandura zvinhu pachayo kuburikidza nekuita kwemakemikari. Mirayiridzo mikuru yekugadzirisa yakavakirwa pakuvandudzwa kwekushanda kwakanangwa ndeiyi inotevera:

Chiziviso Chakakosha: Mumakore achangopfuura, kugadziriswa kwezvinodzivirira moto kwave kuri pamberi pekutsvaga. Semuenzaniso, ongororo yakaitwa munguva pfupi yapfuura yakashandisa chitosan ne cerium ions zvakabva mu bio-based uye rare-earth cerium ions kugadzirisa APP yechinyakare inodzivirira moto. Kuwedzera huwandu hushoma chete kwakaderedza zvakanyanya kudonha kwemvura inonyunguduka panguva yekupiswa kweTPU uye kwakaderedza zvakanyanya kuburitswa kweutsi hune chepfu, zvichiita kuti pave nekushanda kwakaringana uye hushamwari pakati pezvakatipoteredza.
II. Maitiro Akakosha Ekugadzira
Kugadzirisa zvinhu zvinobudirira kunoenderana nekusarudza nzira chaiyo yekugadzirisa.
- Kusanganisa Kunyungudutsa
- Maitiro: TPU matrix inopiswa kusvika yanyungudutswa ine zvinhu zvakasiyana-siyana zvinogadzirisa (zvinodzivisa moto, zvinozadza, zvinogadzirisa purasitiki, nezvimwewo) mu extruder. Simba guru rekuchekerera sikuruu rinoita kuti pave nekusanganiswa kwakafanana, zvichiteverwa ne extrusion uye pelletizing.
- Zvinhu Zvakanakira: Iyi ndiyo nzira inonyanya kushandiswa mumaindasitiri uye yakakura. Maitiro acho ari nyore uye akakodzera kugadzirwa kwezvinhu zvakawanda.
- Kugadzira Makemikari Munzvimbo/Kugadzira Makemikari
- Maitiro: Zvinogadzirisa zvine mapoka chaiwo anoshanda (semuenzaniso, zvinodzora moto zvinogadzirisa) zvinosanganiswa zvakananga muTPU molecular main chain panguva yepolymerization stage (imwe-shot kana prepolymer method).
- Zvimiro: Inopa mhedzisiro inogara kwenguva refu uye yakagadzikana uye inoramba ichishanda zvakanaka, kunyangwe ichisanganisira kuoma kwehunyanzvi uye mutengo wakakwira.
- Kurapa Kwepamusoro
- Maitiro: Pamusoro pezvigadzirwa kana mafirimu eTPU akatogadzirwa kare anogadziriswa kuburikidza nekorona, kurapwa kweplasma, kana kuputira nezvinhu zvinobatanidza (semuenzaniso, silane) kuti ichinje hunhu hwayo hwemakemikari kana chimiro chayo.
- Zvakanakira: Hazvichinje hunhu hwezvinhu zvakawanda, zvinongovandudza kunamira kwepazasi, kudhindwa, kana kushanduka kwemvura. Yakanakira mafirimu nependi.

IV. Mhedziso uye Zano reKusarudza Zvinhu
Muchidimbu, musimboti mukuru wekuchinja kweTPU ndewekutarisa kusasimba kwekushanda kweTPU uye, kuburikidza nenzira dzemuviri kana dzemakemikari, kuisa zvinhu zvinopindirana kuti uwane kusimudzira kushanda kwakatarisana.
Kune makambani nenyanzvi dzeR&D, kusarudza nzira chaiyo yekugadzirisa kunogona kutevera nzira iyi iri nyore yekusarudza:
- Tsanangura Maitiro Ekushandisa: Ndezvezvinhu zvemagetsi zvinobvira moto here? Kunyudzwa mumvura kwenguva refu here? Kana kuti kusvikwa panze here?
- Tsvaga Mapoka Akakosha Ekushanda: Zvichibva pane zvakaitika, tsvaga nzvimbo inonyanya kukosha apo TPU yakajairwa inokundikana (semuenzaniso, kunonoka kwemurazvo, kuramba hydrolysis).
- Sarudza Sisitimu Yakakodzera Yekugadzirisa: Uchifunga nezvekushandisa mari uye kugona kwekugadzirisa, sarudza mhando yekuchinja inoenderana uye maitiro akatsanangurwa pamusoro apa.
At Yantai Linghua New Material Co., Ltd., hatingopi zvinhu chete; tinoshanda pamwe chete nevatengi vedu kuti tigadzire mhinduro pamwe chete. Chikwata chedu chehunyanzvi chakagadzirira kushanda nemi kuti tiongorore zvamunoda uye tipe mazano kana kuti tigadzirewo pamwe chete fomura yakagadziridzwa yeTPU yekushandisa kwenyu.
Kuti uwane rumwe ruzivo kana kukurukura nezve fomura yakagadzirwa, ndapota taura nesu.
