Ukukhanya okuphezulu okulastiki okusingqongileyo-friendly EVA ukulungiswa kwezinto ezinogwebu

chaza:

Izinto ezinogwebu ze-EVA luhlobo lwemathiriyeli yogwebu eyenziwe nge-EVA (ethylene-vinyl acetate copolymer) kunye ne-low-density polyethylene (LDPE) njengezinto ezikrwada kunye nezinye izongezo.Inokuguquguquka okuhle, ukunwebeka okufana nerabha, ukungafihli kakuhle kunye neglosi yomphezulu, uzinzo oluhle lweekhemikhali, ukulwa nokuguga, kunye nokumelana ne-ozone, okungeyona ityhefu.

Iinkcukacha zeMveliso
Iithegi zeMveliso

Abantu abaninzi bacinga ukuba imathiriyeli yogwebu ye-EVA yindibaniselwano egqibeleleyo yeqokobhe eliqinileyo kunye neqokobhe elithambileyo, Nangona kunjalo, ukusetyenziswa kwezinto ezinogwebu ze-EVA kuthintelwe kumlinganiselo othile ngenxa yokungagugi, ukumelana nokuguquguquka, ukuqina, kunye nokuxhathisa kwe-abrasion.Ukunyuka kwe-ETPU kwiminyaka yakutshanje kunye nokuthelekiswa kweesampulu kwenza izihlangu ezinogwebu ze-EVA kufuneka zibe nobunzima obuphantsi, ukuphindaphinda okuphezulu, ukuguqulwa koxinzelelo oluphantsi, kunye nezinye iipropathi ezintsha kunye neemveliso ezinogwebu ze-EVA ezibonelelwe kwimarike ngoku zilungiswa ngendlela yekhemikhali yogwebu. kwaye zisetyenziswa ikakhulu kwiimveliso ezifana nempahla yezihlangu, iimethi zomhlaba, kunye nezinto ezinjalo ezidibana ngqo nemizimba yabantu.Nangona kunjalo, izinto ezinogwebu ze-EVA ezilungiselelwe yindlela kunye nenkqubo inokhuseleko lokusingqongileyo kunye neengxaki zempilo, kwaye ngokukodwa, izinto ezinobungozi (ingakumbi i-formamide) zihlala zihlukaniswa ngaphakathi kwemveliso ixesha elide.

Iingxaki ezithile zezi zilandelayo: okokuqala, iqondo lobushushu lokubola kwi-agent egwebu iikhemikhali kufuneka libe ngaphezu kweqondo lobushushu apho i-EVA isondele ekunyibilikeni yinkqubo ye-EVA yekhemikhali yogwebu, kwaye iqondo lobushushu lokubola kwe-agent egwebu imichiza libanzi kakhulu. kunye nenkqubo yokubola ibandakanya ibhalansi yeekhemikhali, ukwenzela ukuba i-agent yekhemikhali igwebu isasele kwisixa esikhulu kwi-matrix yezinto eziphathekayo emva kokuba ugwebu lugqityiwe, imilinganiselo yokucoca i-EVA yobushushu obuphantsi kwimeko enganyibilikiyo kunye nokwandisa ukongezwa koluhlu lwezinto ezincedisayo. ii-arhente ezifana ne-agent edibanisayo, i-stearic acid, i-cross-linking initiator, i-agent egwebu i-agent yokubola i-catalyst, i-plasticizer kunye nezinye ezilolu hlobo zamkelwe ikakhulu kwishishini lokunciphisa impembelelo ye-agent eshiyekileyo yogwebu ekusebenzeni kogwebu. izinto eziphathekayo, kodwa amanyathelo ngokuthe ngqo abangela isixa esikhulu micromolecular agents ancedisayo lula ukufudukela kwimveliso yokugqibela, kunye neearhente ezincedisayo ngokuqhubekayo ukufudukela kumphezulu wemveliso ukusuka ngaphakathi kunye nokusetyenziswa ixesha elide, ukuze usulelo ulusu okanye olunye ungcoliseko oludityaniswe nemveliso lubangelwa;okwesibini, kwinkqubo yogwebu lwekhemikhali, ukubola kwearhente yokuvuthela imichiza emisela indlela yokuziphatha enogwebu kunye nokuwela imichiza emisela indlela yokuziphatha enyibilikayo yerheology iqhubeke ngaxeshanye, kwaye iqondo lobushushu elilungele ukubola kwearhente yokuvuthela imichiza ayilobushushu obulungele kakhulu. inyibilika i-rheology ye-cell nucleation kunye nokukhula.Ukongeza, i-agent yekhemikhali ye-foaming agent kunye ne-chemical crosslinking yinkqubo eguquguqukayo eyenziwa ngokuqhubekayo kunye nexesha, kwaye ukuxhomekeka kobushushu kunamandla kakhulu.Inkqubo yokulungiselela i-EVA igwebu ngendlela yekhemikhali ye-foaming idinga ukuqwalasela ukudibanisa kunye nokuphosa amagwebu ngaxeshanye ukuze ukulungelelaniswa kwesakhiwo seseli kunzima.

Ukuze kulungiswe ezi ngxaki zingasentla, abavelisi bezinto eziphathekayo baye baqhuba uphando kunye nokufunda.udibaniso lwempahla enegwebu ye-EVA kunye nezinye izixhobo ze-elastomer ziye zaba luphando olushushu phakathi kwabavelisi bezihlangu.

I-SILIKE Si-TPV i-thermoplastic elastomer yi-lastomer eguquguqukayo ye-thermoplastic esekelwe kwi-thermoplastic eyenziwe ngobuchwepheshe obukhethekileyo obuhambelanayo ukunceda irabha ye-silicone ehlakazwe kwi-EVA ngokulinganayo njenge-1 ~ 3 yamasuntswana e-micron phantsi kwe-microscope.Ezo zixhobo zahlukileyo zidibanisa amandla, ukuqina, kunye nokuxhathisa kwe-abrasion yayo nayiphi na i-elastomer ye-thermoplastic eneempawu ezinqwenelekayo ze-silicone: ukuthamba, ukuvakala kwesilika, ukukhanya kwe-UV, kunye nokumelana neekhemikhali ezinokuphinda zisetyenziswe kwaye ziphinde zisetyenziswe kwiinkqubo zokwenziwa kwemveli.
