Ifilimu ye-TPU engekho tyheli ene-PET eyodwa ekhethekileyo ye-PPF Lubrizol imathiriyeli
Malunga neTPU
Isiseko sezinto eziphathekayo
Ukubunjwa: Ukwakhiwa okuphambili kwefilimu engenanto ye-TPU yi-thermoplastic polyurethane elastomer, eyenziwa yi-polymerization ye-reaction ye-diisocyanate molekyuli ezifana ne-diphenylmethane diisocyanate okanye i-toluene diisocyanate kunye ne-macromolecular polyols kunye ne-polyols ephantsi ye-molecular.
Iipropati: Phakathi kwerabha kunye neplastiki, kunye noxinzelelo oluphezulu, uxinzelelo oluphezulu, olunamandla kunye nezinye
Uncedo lwesicelo
Khusela ipeyinti yemoto: ipeyinti yemoto ihlukanisiwe kwindawo yangaphandle, ukuphepha i-oxidation yomoya, ukubola kwemvula ye-asidi, njl., kwintengiso yemoto yesibini, inokukhusela ngokufanelekileyo ipeyinti yokuqala yesithuthi kunye nokuphucula ixabiso lesithuthi.
Ulwakhiwo olufanelekileyo: Ngokuguquguquka okuhle kunye nokunwebeka, inokulingana kakuhle indawo egobileyo yemoto, nokuba yinqwelomoya yomzimba okanye inxalenye ene-arc enkulu, inokufezekisa ukufaneleka okuqinileyo, ukwakhiwa okulula, ukusebenza okuqinileyo, kunye nokunciphisa iingxaki ezinjengamaqamu kunye nokugoba kwinkqubo yokwakha.
Impilo yokusingqongileyo: Ukusetyenziswa kwezinto ezinobungane bokusingqongileyo, ezingenabungozi kwaye zingenancasa, zihambelana nokusingqongileyo, kwimveliso kunye nokusetyenziswa kwenkqubo akuyi kubangela ingozi kumzimba womntu kunye nokusingqongileyo.
Isicelo
Iimoto zangaphakathi kunye nangaphandle, ifilimu ekhuselayo yezindlu zesixhobo sombane, ukunxitywa kwecatheter yezonyango, iimpahla, izihlangu, ukupakishwa

Iphakheji
1.56mx0.15mmx900m/roll,1.56x0.13mmx900/roll, yenziweiplastikiipalethi
Ukuphatha kunye noGcino
1. Kuphephe ukuphefumla umsi wokulungiswa kwe-thermal kunye nomphunga
2. Izixhobo zokuphatha oomatshini zinokubangela ukubunjwa kothuli. Kuphephe ukuphefumla uthuli.
3. Sebenzisa iindlela ezifanelekileyo zokumisa xa uphethe le mveliso ukuphepha iintlawulo ze-electrostatic
4. Iipellets emgangathweni zingatyibilika kwaye zibangele ukuwa
Iingcebiso zokugcina: Ukugcina umgangatho wemveliso, gcina imveliso kwindawo epholileyo, eyomileyo. Gcina kwisitya esivaliweyo.
