IiResins zePVC zePremium SG3, SG5, SG7: Ubunjineli obulungiselelwe izisombululo zoshishino zokuphela ukuya ekupheleni
Uyilo lweeMolekyuli kunye neempawu zomzimba
I-SG3 (Umgangatho oPhezulu wokuguquguquka)
Yenziwe nge-polymerization degree ye-1300 - 1500 kunye ne-K - ixabiso le-70 - 72, le grade inee-molecular chain ezinde eziphucula ukubanjwa kwe-plasticizer. Ukusasazwa kwayo kwamasuntswana angama-60 - 250μm kuqinisekisa ukusasazwa okufanayo kwiifomyula ezithambileyo, okuvumela ukufunxwa kwe-plasticizer engama-25 - 35g kwi-resin ye-100g nganye. Isakhiwo esingenasimo esibonakalayo sinika ubude obugqwesileyo xa kuqhekeka, okwenza kube yeyona ifanelekileyo kwiimveliso ezifuna ukugoba ngokuphindaphindiweyo ngaphandle kokuqhekeka.
I-SG5 (Iyasebenziseka Kakhulu - Udidi Oluphakathi)
Ilungelelanisa i-polymerization degree ye-1000 - 1100 kunye ne-K - value ye-65 - 67, i-SG5 inika umgangatho ophakathi oguqukayo. Uxinano lwayo oluphuculweyo lwe-particle (0.45 - 0.58g/mL) lwenza kube lula ukuhamba kwe-melt okugudileyo kokubini kwi-extrusion nakwi-injection molding, ngelixa ukufunxwa kwe-plasticizer okuphakathi (20 - 28g/100g) kwenza kube lula ukutshintsha ukusuka kwi-semi-rigid cable sheaths ukuya kwi-low-flexibility profiles. Ukuhlala rhoqo kwe-molecular chain kunciphisa iziphene zokucubungula, kuqinisekisa ukuba ubukhulu bodonga buhlala bufana kwi-extrusion yepayipi.
I-SG7 (Udidi loBunjineli obuQondileyo)
Ngesidanga sepolymerization se-700 - 850 kunye ne-K - ixabiso le-60 - 62, i-SG7 ibeka phambili ukusebenza kakuhle kokupakisha kwe-molecular ukuze kube nokuqina. Ulwakhiwo lwayo oluncinci lwe-40 - 180μm yamasuntswana (ubuninzi be-0.50 - 0.62g/mL) lunciphisa izithuba kwiindawo ezibunjiweyo, nto leyo ephucula ukumelana nempembelelo kwiprofayili zokwakha. Ukufunxwa kweplastiki ephantsi (15 - 22g/100g) kuvumela iifomyula eziqinileyo ngokupheleleyo, ngelixa i-residual vinyl monomer ≤3μg/g ihlangabezana nemigangatho yokhuseleko lokuqhagamshelana nokutya kwizicelo zokupakisha.
Inkqubo yesicelo
SG3: Ingcali yokuguquguquka
Kwicandelo lezolimo, iifilimu ezisekelwe kwi-SG3 ezine-40 - 50 phr ezongeziweyo ze-plasticizer zenza izigqubuthelo ze-UV ezizinzileyo ze-greenhouse, ezilungelelanisa ukuhanjiswa kokukhanya kunye namandla okumelana neenyembezi. Kwiinkqubo zonyango, umxholo wayo ophantsi we-monomer uvumela iityhubhu ezithambileyo kwiimashini ze-dialysis, ngelixa kwizihlangu, idala imiphetho ye-elastiki egcina imo kuyo yonke imozulu eguquguqukayo.
SG5: Ihashe Elisebenzayo Kwimizi-mveliso
Abavelisi beentambo basebenzisa uluhlu lwe-SG5 lwe-10 - 20 phr plasticizer ukuvelisa iishelufu zokukhusela umlilo ezigcina ilangatye kwiigridi zamandla, zidibanisa ukhuseleko lombane kunye nokuqina koomatshini. Ekwakhiweni kwayo, iphuma kwiistrip zokuvala ezimelana nemozulu kwiifestile, apho ubunzima bayo obuphakathi bumelana nokuwohloka kwe-ozone. Izixhobo zemoto ezibunjiweyo, ezifana nee-trims zocango, ziyaxhamla kumlinganiselo wayo woxinzelelo-ubunzima-ukuya-kubunzima.
I-SG7: Intshatsheli yoBulukhuni
Iinkqubo zemibhobho yemizi-mveliso zixhomekeke kwi-modulus ephezulu ye-SG7 kwiipayipi zemibhobho ye ...
Isikhokelo sokuSebenzisa iiNkqubo
IiNgcamango zoLawulo loBushushu
I-SG3 ifuna ulawulo oluqinileyo lobushushu (160 - 180°C) ukuthintela ukubola kwangaphambi kwexesha; nokuba i-10°C idubula kakhulu inokubangela ukukhululwa kwe-hydrochloric acid, okukhokelela ekubeni ibe tyheli. Ngokwahlukileyo koko, i-SG7 inyamezela ukucutshungulwa kwe-180 - 200°C, okuvumela amazinga okuphuma ngokukhawuleza kwimibhobho emikhulu, nangona i-210°C inokuba yingozi yokuqhekeka kwe-molecular chain.
Uyilo lweNkqubo yoNcedo
Ukuzinza: I-SG3 ifuna i-1 - 2 phr ye-calcium - zinc composite stabilizers ukuze ilwe nokuwohloka kobushushu ngexesha lokucubungula i-plasticizer ephezulu, ngelixa i-SG7 ifuna i-0.5 - 1 phr kuphela ngenxa yoxinzelelo oluncitshisiweyo olubangelwa yi-plasticizer.
Ukuthambisa: Zonke iiklasi zixhamla kwi-0.2 - 0.5 phr ye-wax ye-polyethylene, kodwa i-SG3 ingafuna iidosi eziphezulu ukunciphisa ukungqubana kwangaphakathi kwiikhompawundi ezithambileyo.
Izithako ezisebenzayo: Ii-Antioxidants kwi-SG7 formulations zandisa ubomi benkonzo yangaphandle, ngelixa iziguquli zempembelelo kwi-SG5 zonyusa ukumelana ne-notch kwizicelo zemozulu ebandayo.
Ubuchule boBunjineli kuYilo lweResin
Ngokudibanisa ubunjineli beemolekyuli obuchanekileyo kunye novavanyo oluqhutywa yisicelo, ipotifoliyo yethu ye-SG3, SG5, SG7 inika amandla abavelisi ukuba badlule kwimida yesiqhelo ye-PVC. Ukususela ekuguquguqukeni okufunekayo kwizinto zonyango ezilahlwayo ukuya kubunzulu besakhiwo obufunekayo kulwakhiwo oluphezulu, ezi resin zimele ukuhlanganiswa kobungqongqo besayensi kunye nokusebenza kwemizi-mveliso—ukubeka imilinganiselo emitsha yezisombululo zepolymer eziqhutywa yintsebenzo.
