Igama lemveliso:i-polyethylene
Imo yemolekyuli:nC2H4
Inombolo yeCAS:9002-88-4
Ulwakhiwo lwemolekyuli yemveliso:
Iipropati zeMichiza kunye nezomzimba zichaphazeleka ngokuphawulekayo ngokunyuka koxinaniso, oluchatshazelwa yimilo kunye nesithuba sekhonkco le-molecular. Iimathiriyeli ezinoxinano oluphantsi zinamatyathanga amasebe kunye nezithuba ezibanzi, ngelixa izinto ezixineneyo zithe ngqo kwaye zihambelana ngokusondeleyo. I-Polyethylene yoxinaniso oluphantsi (0.926–0.9409 g/cm3) iyanyibilika kwizinyibilikisi zendalo kumaqondo obushushu angaphezu kwama-200°F. Ayinyibiliki kwiqondo lobushushu begumbi. I-polyethylene ephezulu (0.041-0.965 g / cm3) i-hydrophobic, ingena kwi-gas, kwaye inokumelana nombane ophezulu.
Iipolyethylenes ezinobunzima obuphantsi bemolekyuli zinokuxhathisa umbane okugqwesileyo kunye nokumelana namanzi kunye neekhemikhali ezininzi. Iipolima ezinobunzima bemolekyuli obuphakathi zii-wax ezixubeneyo kunye neparafini, kunye neepolima zepolyethylene ezinobunzima bemolekyuli obungaphezulu kwe-10,000 zezona ziqhelekileyo iintlaka eziqinileyo nezithambileyo okanye eziqinileyo. Ngokwahluka kwe-catalyst kunye neendlela zepolymerization, iipropathi ezinje ngoxinaniso, icrystallinity, ubunzima bemolekyuli, kunye ne-polydispersity inokulawulwa kuluhlu olubanzi. Iipolymers ezinoxinano ukusuka malunga ne-0.910 ukuya kwi-0.925 g / cm3 ziyi-polyethylenes ephantsi; abo banoxinano ukusuka kwi-0.926 ukuya kwi-0.940 g / cm3 yi-polyethylenes yoxinaniso oluphakathi; kwaye abo baxineneyo ukusuka kwi-0.941 ukuya kwi-0.965 g/cm3 nangaphezulu zii-polyethylenes ezixineneyo.
I-Polyethylene (PE) yipolymer ye-thermoplastic equka amatyathanga e-hydrocarbon amade. I-PE isetyenziswe kwinani lezicelo ezibandakanya ukupakishwa kwefilimu eguquguqukayo eveliswa yinkqubo yefilimu evuthelweyo. I-Polyethylene isetyenziselwa ukulawula i-viscosity, iipropati zokumiswa, kunye nokuzinza ngokubanzi kwiifom ze-cosmetic. Usetyenziso oluqhelekileyo lubandakanya iindawo ezibunjiweyo zesitofu esikhethekileyo, kwezi ndawo iPolyethylene inoluhlu olubanzi losetyenziso:
Isitofu kunye nokuvuthela izinto zokudlala ezibunjiweyo, izinto zendlu kunye neziciko.
Isitofu sezihlalo zemoto ezibunjiweyo, iindawo zokucheba kunye neepeyile.
Isitofu esibunjiweyo, izikhongozeli ezinodonga olucekethekileyo kunye nezinto zasendlini.
I-hot melt coating yephepha, i-additive in cast moldings, amakhandlela, i-oyile-based inki kunye ne-adhesives eshushu enyibilikayo.
Ukongezwa kwiipolyester ezingaxutywanga, ii-epoxides kunye nezinye iipolymers ukunika iimpawu ezizodwa ze-UHMWPE. Isetyenziswe kwiindawo zoshishino, iingubo kunye neendawo zokunxiba kwi-10-40 wt. %.
Izicelo zefilimu ezinobunzima obuhle kunye nokuqina.
Isongezo sokukhupha umngundo, i-lubricant kwi-rubber processing, i-extrusion kunye ne-calendering aid ye-PVC kunye nokuncedisa ukusabalalisa ukugxila kombala.
Iibheringi, iigiya, iibhutsi kunye nezinye iindawo ezihambayo.
iityhubhu zeLabhoratri; ekwenzeni iiprothes; ukugqunywa kombane; izinto zokupakisha; izixhobo zasekhitshini; itanki kunye neentambo zombhobho; iingubo zephepha; iimpahla eziqinileyo.
i-polyethylene isetyenziselwa ukulawula i-viscosity, iipropati zokunqunyanyiswa, kunye nokuzinza ngokubanzi kwi-cosmetic formulations. Isuka kwi-petroleum gas okanye ukuchithwa kotywala.
I-Chemwin inokubonelela ngoluhlu olubanzi lwee-hydrocarbons ezininzi kunye nezinyibilikisi zeekhemikhali kubathengi bamashishini.Ngaphambi koko, nceda ufunde olu lwazi lulandelayo olusisiseko malunga nokwenza ishishini nathi:
1. Ukhuseleko
Ukhuseleko yeyona nto iphambili kuthi. Ukongeza ekunikeni abathengi ngolwazi malunga nokusetyenziswa ngokukhuselekileyo nokuhambelana nokusingqongileyo kweemveliso zethu, sikwazimisele ekuqinisekiseni ukuba imingcipheko yokhuseleko lwabasebenzi kunye neekontraka ziyathotywa ukuya kutsho kubuncinane obufanelekileyo nobunokwenzeka. Ngoko ke, sifuna ukuba umthengi aqinisekise ukuba imigangatho efanelekileyo yokukhutshwa kunye nokugcinwa kwemigangatho yokhuseleko idibene ngaphambi kokunikezelwa kwethu (nceda ubhekisele kwisihlomelo se-HSSE kwimimiselo jikelele kunye neemeko zokuthengisa ngezantsi). Iingcali zethu zeHSSE zinokubonelela ngesikhokelo kule migangatho.
2. Indlela yokuhambisa
Abathengi banokuodola kwaye bahambise iimveliso kwi-chemwin, okanye banokufumana iimveliso kwisityalo sethu sokuvelisa. Iindlela ezikhoyo zothutho ziquka iilori, uloliwe okanye uthutho lweendlela ezininzi (kuyasebenza iimeko ezahlukileyo).
Kwimeko yeemfuno zabathengi, sinokucacisa iimfuno zeenqanawa okanye iitanki kwaye sisebenzise imigangatho ekhethekileyo yokhuseleko / ukuhlaziya kunye neemfuno.
3. Ubuncinci bobungakanani bomyalelo
Ukuba uthenga iimveliso kwiwebhusayithi yethu, ubungakanani obuncinci bomyalelo ziitoni ezingama-30.
4.Intlawulo
Indlela yokuhlawula eqhelekileyo itsalwa ngokuthe ngqo kwiintsuku ezingama-30 kwi-invoyisi.
5. Amaxwebhu okuhanjiswa
La maxwebhu alandelayo anikwe ngokuziswa ngakunye:
