Igama lemveliso:ipolyester
Ulwakhiwo lwemolekyuli yemveliso:
I-polyester luhlobo lweepolymers eziqulathe iqela elisebenzayo le-ester kuyo yonke iyunithi yokuphinda yekhonkco labo eliphambili.Njengesixhobo esithile, ngokuqhelekileyo sibhekisela kuhlobo olubizwa ngokuba yi-polyethylene terephthalate (PET).Iipolyester ziquka iikhemikhali ezenzeke ngokwemvelo, kwizityalo nakwizinambuzane, kunye nezinto zokwenziwa ezifana ne-polybutyrate.Iipolyester zendalo kunye nee-synthetic ezimbalwa ziyakwazi ukubola, kodwa i-polyester ezininzi zokwenziwa azikho.Iipolyester zokwenziwa zisetyenziswa kakhulu kwiimpahla.Iintsinga zePolyester ngamanye amaxesha zijijwa kunye neentsinga zendalo ukuvelisa ilaphu elineempawu ezidityanisiweyo.Imixube ye-cotton-polyester inokuba namandla, imibimbi- kunye ne-resistant-resistant-resistant, kunye nokunciphisa ukucutheka.Iintsinga ze-Synthetic zisebenzisa i-polyester zinamanzi aphezulu, umoya kunye nokumelana nokusingqongileyo xa kuthelekiswa nemicu yezityalo.Azikwazi ukumelana nomlilo kwaye zinokunyibilika xa zibasiwe.Iipolyester zecrystalline elulwelo ziphakathi kwezokuqala ngqa kwimizi-mveliso yeepholima zekristale ezingamanzi.Zisetyenziselwa iipropati zabo zomatshini kunye nokumelana nokushisa.Ezi mpawu zikwabalulekile kwisicelo sazo njengetywina elinokuchithwa kwiinjini zejethi.Iipolyester zendalo zazinokuba nendima ebalulekileyo kwimvelaphi yobomi.Amakhonkco amade e-polyester kunye nezakhiwo ezingenayo i-membrane ziyaziwa ukuba zenze lula kwi-reaction-pot reaction ngaphandle kwe-catalyst phantsi kweemeko ezilula ze-prebiotic.
Ilaphu elilukiweyo okanye elinithiweyo ngentambo yepolyester okanye intambo isetyenziswa kakhulu kwimpahla nakwimpahla yasekhaya, ukusuka kwiihempe neebhulukhwe ukuya kwiibhatyi neminqwazi, amalaphu ebhedi, iingubo, ifenitshala exhonyiweyo kunye neemethi zempuku zekhompyutha.Iintsinga zepolyester zoshishino, iintambo kunye neentambo zisetyenziselwa ukuqiniswa kwamatayara emoto, amalaphu amabhanti okuhambisa, amabhanti okhuseleko, amalaphu agqunyiweyo kunye nokuqiniswa kweplastiki ngokufunxa amandla aphezulu.Ifiber yePolyester isetyenziswa njenge cushioning kunye ne insulating material kwi pillows, comforters kunye ne upholstery padding.Amalaphu epolyester ayakwazi ukumelana nebala—eneneni, ekuphela kodidi lwedayi olunokusetyenziswa ukuguqula umbala welaphu lepolyester koko kwaziwa njengedayi esasazwayo.[19]Iipolyester zikwasetyenziselwa ukwenza iibhotile, iifilimu, i-tarpaulin, iiseyile (i-Dacron), amaphenyane, iziboniso zekristale zamanzi, iihologram, izihlungi, ifilimu ye-dielectric ye-capacitors, ukugquma ifilimu kwi-wire kunye ne-insulating tapes.Iipolyester zisetyenziswa ngokubanzi njengokugqiba kwiimveliso zokhuni ezikumgangatho ophezulu ezifana neziginkci, ipiyano kunye nemoto/yacht yangaphakathi.Iimpawu ze Thixotropic ze-polyester ezisetyenziselwa ukutshiza zenza ukuba zilungele ukusetyenziswa kwiiplanga ezivulekileyo, njengoko zikwazi ukuzalisa ngokukhawuleza iinkozo zokhuni, kunye nobukhulu befilimu obuphezulu kwingubo nganye.Ingasetyenziselwa iilokhwe ezisefashonini, kodwa ithandwa kakhulu ngamandla ayo okumelana nemibimbi kunye nokuhlambeka kwayo lula.Ukuqina kwayo kuyenza ibe lukhetho oluqhelekileyo lokunxitywa kwabantwana.Ipolyester ihlala idityaniswa nezinye iintsinga ezinjengomqhaphu ukufumana ezona hlabathi zimbini.Iipolyester eziphilisiweyo zinokuthi zenziwe ngesanti kwaye ziphuculwe kwi-gloss ephezulu, ehlala ixesha elide.
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:
· Ibhili yokuLading, i-CMR Waybill okanye olunye uxwebhu olufanelekileyo lwezothutho
· Isatifikethi sokuHlalutya okanye ukuThobela (ukuba siyafuneka)
· Amaxwebhu anxulumene neHSSE ngokuhambelana nemigaqo
· Amaxwebhu ezinto eziqhelekileyo ngokuhambelana nemigaqo (ukuba kuyafuneka)
