Ama-PVC Resins we-Premium SG3, SG5, SG7: Ubunjiniyela Obulungiselelwe Iinsombululo Zebubulo
Umklamo wamamolekhyuli kanye neemfanelo eziphathekako
SG3 (Izinga eliphezulu - lokuTjhuguluka)
Yenziwe nge-polymerization degree engu-1300 - 1500 kanye ne-K - value engu-70 - 72, igreyidi le inamaketanga amade wamamolekhyuli akhuphula ukubanjwa kweplastiki. Ukusabalala kwayo okungu-60 ukuya ku-250μm kuqinisekisa ukusabalala okufanako eenhlanganisweni ezithambileko, okuvumela ukumuncwa kweplastiki okungu-25 ukuya ku-35g nge-100g ye-resin. Isakhiwo esingabonakaliko esiphumelako sinikela ukunwebeka okukhethekileko lokha nakuphukako, okwenza bona kube kuhle emikhiqizweni efuna ukugoba ngokuphindaphindiweko ngaphandle kokuqhekeka.
SG5 (Ubujamo obuhlukahlukeneko - Ibanga)
Ukulinganisa izinga lokubumbana elingu-1000 ukuya ku-1100 ngenani le-K elingu-65 ukuya ku-67, i-SG5 inikela ngendawo ephakathi enamandla. Ukuminyana kwayo okulungisiweko (0.45 - 0.58g/mL) kwenza kube lula ukugeleza okutjhelelako kokubili kokukhipha nokujova, ngesikhathi ukumuncwa kweplastiki okulinganiselweko (20 - 28g/100g) kwenza ukutjhuguluka ukusuka emakhebuleni aqinileko ukuya kumaphrofayili aphasi. Ukulandelana kweketango lamamolekhyuli kunciphisa ukukhubazeka kokucubungula, ukuqinisekisa ukuqina kweboda okufanako ekukhutjhweni kwepayipi.
SG7 (Ibanga lobunjiniyela eliqinileko)
Nge-polymerization degree engu-700 - 850 kanye ne-K - value engu-60 - 62, i-SG7 iqakathekisa ukusebenza kuhle kokupakisha kwamamolekhyuli ukuqina. Isakhiwo sayo esincani esingu-40 ukuya ku-180 μm (ubukhulu obungu-0.50 - 0.62g/mL) sinciphisa iinkhala eengcenyeni ezibunjiweko, okwenza bona kube nokujamelana nomthelela emaphrofaylini wokwakha. Ukumuncwa kweplastiki okuphasi (15 - 22g/100g) kuvumela ukwakheka okuqinileko, ngesikhathi i-vinyl monomer eseleko ≤3μg/g ihlangabezana namazinga wokuphepha kokudla - ukuthintana malungana nokuphakheja.
Ihlelo lokusebenza
SG3: Ingcwethi yokuTjhuguluka
Emikhakheni yezokulima, amafilimu asekelwe ku-SG3 anama-40 - 50 phr weplastiki akha iimvalo ze-UV - ezizinzileko ze-greenhouse, ukulinganisa ukudluliswa kokukhanya namandla wokujamelana nokudabuka. Ekusetjenzisweni kwezokwelapha, okuqukethwe kwayo okuphasi kwe-monomer kwenza bona kube namatjhubhu athambileko wemitjhini yokuhlanza, lokha eenyaweni, yenza amasole we-elastic agcina ubujamo lokha nakutjhuguluka amazinga womtjhiso.
SG5: I-Industrial Workhorse
Abakhiqizi bamakheyibuli basebenzisa i-SG5's 10 - 20 phr plasticizer range ukukhiqiza ama-sheaths wokuvikela amalangabi wamagridi wamandla, ukuhlanganisa ukuvikela igezi nokuqina kwemitjhini. Ekwakhiweni, iphuma ibe yimitjhini yokuvala amafasitela, lapho ukuqina kwayo okulinganiselweko kujamelana nokuwohloka kwe-ozone. Iingcenye zeenkoloyi ezibunjwe nge-injection, ezifana nama-trim weminyango, zizuza ekutheni kwazo - amandla - ukuya - esilinganisweni sesisindo.
SG7: Iqhawe lokuqina
Iinhlelo zamapayipi wezebubulo zithembele ku-SG7's modulus ephezulu yamaphayiphi we-sewer ajamelana namakhemikhali kanye namaphayiphi wamanzi anegandeleleko. Amaphrofayili wamafasidera aphumileko, lokha nakahlanganiswa ne-titanium dioxide, atjengisa ukuqina kombala okhethekileko eendaweni zangaphandle. Abakhiqizi be-elekthronikhi bayisebenzisela ukujova - ukubunjwa kwezindlu zezinto zokusebenza, basebenzisa ukuzinza kwayo ngesikhathi sokuhlanganiswa kwamazinga aphezulu womtjhiso.
Umhlahlandlela wokwenza ngcono ikambiso
Ukulawulwa kokuTjhisa
I-SG3 ifuna ukulawulwa okuqinileko kwamazinga womtjhiso (160 - 180°C) ukukhandela ukubola ngaphambi kwesikhathi; ngitjho nokudlula kwe-10°C kungabangela ukukhutjhwa kwe-hydrochloric acid, okudosela ekutheni kube mthubi. Ngokuphikisako, i-SG7 ibekezelela ukucubungula okungu-180 - 200°C, okuvumela amazinga wokuphuma msinyana wamapayipi amakhulu, nanyana ukudlula i-210°C kubeka engozini ukuhlukana kwamaketanga wamamolekhyuli.
Umklamo wehlelo lokungezelela
Ukuzinza: I-SG3 itlhoga i-1 - 2 phr ye-calcium - zinc compositizer ukulwisana nokuwohloka kokutjhisa ngesikhathi sokusetjenziswa kweplastiki ephezulu, kuthi i-SG7 itlhoga i-0.5 - 1 phr kwaphela ngebanga lokunciphisa ukugandeleleka okubangelwa yiplastiki.
Ukuthambisa: Woke amagreyidi azuza ku-0.2 - 0.5 phr ye-polyethylene wax, kodwana i-SG3 ingatlhoga imithamo ephezulu ukunciphisa ukungqubuzana kwangaphakathi kumakhompawundi athambileko.
Iinthako ezisebenzako: Ama-antioxidant ekwakhiweni kwe-SG7 anweba ipilo yangaphandle, ngesikhathi iintjhuguluko eziphathelene ne-SG5 zikhuphula ukujamelana nama-notch ekusetjenzisweni kwamakhaza.
Ubunjiniyela obuhle khulu ekuklameni i-resin
Ngokuhlanganisa ubunjiniyela bemolekhyuli obuqondileko nokuhlolwa okuqhutshwa kusetjenziswa, iphothifoliyo yethu ye-SG3, SG5, SG7 inikela abakhiqizi amandla wokudlula imikhawulo ye-PVC yendabuko. Kusukela ekuguquguqukeni okutlhogekako kwezinto ezilahlwako zokwelapha ukuya ekuthembekeni kwesakhiwo okufunwako ekwakhiweni okuphakemeko, ama-resin la ahlanganisa ukuhlanganiswa kobukhali bezesayensi nokusebenza kwezebubulo—ukubeka amazinga amatjha weensombululo ze-polymer eziqhutshwa ukusebenza.
