Izinto eziluhlaza ze-TPE ziyimveliso ehambelana nokusingqongileyo, engeyona inetyhefu kwaye ikhuselekile, enobunzima obuninzi (0-95A), umbala obalaseleyo, ukubamba okuthambileyo, ukumelana nemozulu, ukumelana nokudinwa kunye nokumelana nobushushu, ukusebenza kakuhle kokusebenza, akukho mfuneko iVulcanized, kwaye ingaphinda isetyenziswe ukunciphisa iindleko, ngoko ke, izinto eziluhlaza ze-TPE zisetyenziswa ngokubanzi kwi-injection molding, i-extrusion, i-blow molding, i-molding kunye nezinye izinto. Ke ngaba uyazi ukuba zeziphi iimfuno zeisitofu sokubumbainkqubo TPE imathiriyeli ekrwada zi? Makhe sibone oku kulandelayo.
Iimfuno zenkqubo yokubumba yenaliti ye-TPE:
1. Yomisa imathiriyeli ekrwada ye-TPE.
Ngokubanzi, ukuba kukho iimfuno ezingqongqo kumphezulu weemveliso ze-TPE, izinto ze-TPE ekrwada kufuneka zomiswe phambi kokubumba inaliti. Kuba kwimveliso yokubumba inaliti, imathiriyeli ekrwada ye-TPE ihlala iqulathe amanqanaba ahlukeneyo okufuma kunye nezinye iipolima ezinobunzima obuphantsi bemolekyuli. Ngoko ke, umthamo wamanzi we-TPE wezinto eziluhlaza kufuneka ulinganiswe kuqala, kwaye abo bamanzi amaninzi kufuneka bomiswe. Indlela yokomisa ngokubanzi kukusebenzisa isitya sokumisa ukomisa kwi-60℃ ~ 80℃ iiyure ezi-2. Enye indlela kukusebenzisa ihopha yegumbi lokomisa, enokuthi ngokuqhubekayo ibonelele ngezinto ezomileyo ezishushu kumatshini wokubumba wokutofa, oluncedo ekwenzeni lula ukusebenza, ukugcina ukucoceka, ukuphucula umgangatho, kunye nokunyusa izinga lokutofa.
2. Zama ukuphepha ukubumba inaliti yobushushu obuphezulu.
Ngaphantsi kwesiseko sokuqinisekisa umgangatho weplastiki, ukushisa kwe-extrusion kufuneka kuncitshiswe ngokusemandleni, kunye noxinzelelo lwe-injection kunye nesantya se-screw kufuneka kwandiswe ukunciphisa i-viscosity yokunyibilika kunye nokuphucula umbane.
3. Seta ubushushu obufanelekileyo benaliti ye-TPE.
Kwinkqubo yokubumba i-TPE yemathiriyeli ekrwada, uluhlu oluseto lobushushu ngokubanzi kwindawo nganye yile: umgqomo we-160 ℃ ukuya ku-210 ℃, umbhobho we-180 ℃ ukuya kwi-230 ℃. Ubushushu bomngundo kufuneka bube phezulu kunobushushu bobushushu bokubumba bendawo yokubumba inaliti, ukuze kuthintelwe imivimbo kumphezulu wemveliso kunye neziphene zesitofu sokubumba iglue ebandayo, ngoko ke iqondo lobushushu lokubumba kufuneka lenziwe ukuba libe phakathi. 30℃ kunye ne-40℃.
4. Isantya sokutofa kufuneka sisuke ngokucotha ukuya kwisantya.
Ukuba ngamanqanaba amaninzi esitofu, isantya sisuka kwisantya ukuya kwisantya. Ngoko ke, igesi ekubunjeni ikhutshwa ngokulula. Ukuba ingaphakathi lemveliso lihlanganiswe ngegesi (ukwandisa ngaphakathi), okanye ukuba kukho izibonda, iqhinga alisebenzi, le ndlela inokulungiswa. Izantya zesitofu esiphakathi kufuneka zisetyenziswe kwiinkqubo ze-SBS. Kwinkqubo ye-SEBS, kufuneka kusetyenziswe isantya esiphezulu sokutofa. Ukuba umngundo unenkqubo eyaneleyo yokukhupha, nokuba inaliti enesantya esiphezulu ayinakukhathazeka malunga nomoya ovalelweyo.
5. Nika ingqalelo ukulawula ubushushu bokusebenza.
Ukushisa okucwangcisiweyo kwezinto eziluhlaza ze-TPE malunga nee-degrees ze-200, kwaye i-TPE ayiyi kubamba umswakama emoyeni ngexesha lokugcinwa, kwaye ngokuqhelekileyo akukho nkqubo yokumisa iyadingeka. Bhaka kwiqondo lokushisa eliphezulu kwiiyure ezi-2 ukuya kwezi-4. I-TPE ifakwe kwi-ABS, i-AS, i-PS, i-PC, i-PP, i-PA kunye nezinye izinto kufuneka zibhakwe kwangaphambili kwaye zibhakwe kwii-80 degrees ze-2 ukuya kwiiyure ze-4.
Isishwankathelo, ziimfuno zenkqubo yokubumba yenaliti ye-TPE. I-TPE ekrwada yimathiriyeli ye-thermoplastic elastomer esetyenziswa ngokubanzi, enokuthi ifakwe isitofu yodwa okanye idityaniswe ngokufudumeleyo ngePP, PE, ABS, PC, PMMA, PBT kunye nezinye izinto zokubumba inaliti yesibini, kunye nezinto ezinokuphinda zisetyenziswe. Ikhuselekile kunye nokusingqongileyo, sele sele isizukulwana esitsha se-rubber ethandwayo kunye neplastiki.
