1, Ukuphucula ubulukhuni kunye nokumelana nempembelelo
Ukuphucula ukuqina: I-CPE, njenge-elastomer, iphucula ubuthathaka be-matrix ye-PVC ngokudibanisa ngokwasemzimbeni, nto leyo ephucula kakhulu amandla empembelelo yezinto ezidityanisiweyo. Uvavanyo lubonise ukuba ukongeza iindawo ezili-10 ze-CPE kunokunyusa amandla empembelelo yezinto ezidityanisiweyo zeplastiki yomthi we-PVC nge-20%. I-CPE ekhethekileyo yeplastiki yomthi yaseTshayina yeBontecn Group inokuphucula kakhulu ukuqina kwemveliso kwaye inciphise iindleko zemveliso. Wamkelekile ukubuza.
Ukulungiswa kokusebenza kakuhle kobushushu obuphantsi: Izinto zokuqinisa uthotho lweemolekyuli eziguquguqukayo ze-CPE ziphucula ukuguquguquka kwazo kwiindawo ezinobushushu obuphantsi, zithintela ukuqhekeka kobushushu obuphantsi.
2, Ukuphucula ukusebenza kokucubungula kunye nokuhambelana
Ukuqinisa uqhagamshelo lwe-interface: Iifayibha zezityalo (ezifana ne-cellulose) ziqulathe inani elikhulu lamaqela e-hydroxyl kwaye azihambelani kakuhle ne-PVC ephobisa amanzi. Iiathom ze-polar chlorine kunye nesakhiwo se-non-polar chain segment ye-CPE zisebenza njenge-"bridge" yokuphucula ukunamathelana phakathi kweefayibha kunye ne-PVC, nto leyo enciphisa ukwahlukana kwesigaba.
Yenza kube lula ukunyibilika: I-CPE inciphisa ukunyibilika, inciphisa ukuwohloka kokutyibilika okubangelwa kukugcwalisa okuninzi komgubo womthi, kwaye yenza ukuxutywa kunye nokubumba okuphumayo kube lula.
Uphononongo lwe-Rheological lubonisa ukuba i-5 phr CPE inokukhuthaza ukwakheka kwejeli ye-PVC kwaye yonyuse i-complex viscosity ye-melt; Kwi-10 parts, i-viscosity iyancitshiswa ukuze ilinganise ukusebenza kakuhle kunye nokusebenza kakuhle kokucubungula.
3, Uphuculo lweempawu ezisebenzayo
Ukuphuculwa kokungavuthwa kwelangatye: Okukhona umxholo we-chlorine we-CPE uphezulu (kungcono i-36-38%), kokukhona isiphumo sokungavuthwa kwelangatye sibaluleke ngakumbi. Iiathom zayo ze-chlorine zikhupha i-hydrogen chloride ngexesha lokutsha ukuze kuthintelwe ukusasazeka kwelangatye.
Ukumelana nemozulu kunye nokuzinza: Ulwakhiwo lwemolekyuli olugcweleyo lwe-CPE lunika izixhobo ezidityanisiweyo ukumelana nokuguga okuhle kakhulu, ukumelana ne-ozone, kunye nokumelana nokugqwala kweekhemikhali, okwandisa ubomi bazo benkonzo yangaphandle.
4, Ulawulo olupheleleyo lweempawu zoomatshini
Ukulinganisela amandla nokuqina: Ubungakanani obufanelekileyo be-CPE (iinxalenye ezi-5-15) bunokuphucula ukuqina ngelixa bugcina amandla okutsala, ukuqina, kunye nokumelana nokurhubuluza kwezinto. Ukongezwa okugqithisileyo kunokukhokelela ekunciphiseni amandla, okufuneka kulawulwe ngokulungiswa kwefomula.
5, Isishwankathelo
I-CPE isombulula iingxaki zokuba buthathaka kakhulu, ukucubungula okunzima, kunye nokutsha kwii-composites zeplastiki zomthi we-PVC ngokusebenzisa indlela yokuqinisa, ukuhambelana kojongano, izixhobo zokucubungula, kunye nokuphucula ukusebenza, ibe yinguqu ephambili yophuhliso lwazo oluphezulu. Ukukhetha i-CPE enomxholo we-chlorine we-35-38% kunye nokwenza ngcono isixa sokongeza (ngesiqhelo iinxalenye ezi-5-15) kunokufezekisa ibhalansi phakathi kokusebenza kunye neendleko.
