Global - Premier PVC S - 1000: Resini ya Polyvinyl Chloride leyi nga Lavekiki

Swihlawulekisi swa Xiviri na Tikhemikhali

Ku languteka: Yihumelela tani hi powder yo basa ya amorphous, na vukulu bya ti particle kusuka eka 60 kuya eka 250μm.
Rendzo: Ku tsindziyela loku vonakaka ku wela eka mpimo wa 0.40 - 0.60g/mL.
Nomboro ya Viscosity ya Xitshunxo: Nhlayo ya viscosity ya dilute solution leyinga na 0.5 grams ya resin eka 100ml ya cyclohexanone i 80 - 160ml/g.
Vuswikoti byo Monya Plasticizer: Eka mahiselo ya kamara, 100g ya resin yinga tswonga 20 - 30g ya plasticizer.
Swikombiso Swin’wana: Nhlayo ya yona ya K - i 65 - 66, degree ya xikarhi ya polymerization yisuka eka 970 kuya eka 1070, naswona nhlayo ya residual vinyl monomer i ≤3ug/g.

Swihlawulekisi swa Xithekiniki

Swikombiso swa Swikumiwa swa giredi ya le henhla: . Nhlayo ya ti volatiles (kukatsa na mati) i ≤0.20%, density leyi vonakaka i 0.50 - 0.58g/mL, nhlayo ya "fish eyes" i ≤10 hi 400cm2, naswona nhlayo ya ti impurity particles i ≤16.
Swihlawulekisi Swin’wana: Malunghana na masalela ya sieve, i ≤2.0% eka 250um sieve hole na ≥95% eka 63um sieve hole.

Tindhawu ta Swikombelo

Switirhisiwa Leswi Cinca-cincaka: Yinga tirhisiwa ku humelerisa tifilimi leti olovaka, maphepha, dzovo ro endliwa, switirhisiwa swa milenge, na swilo swohambana hambana swo olova swa siku na siku - tirhisa. Hiku engetela nhlayo yohambana hambana ya ti plasticizers, switirhisiwa leswingana ti degree tohambana hambana ta ku olova naku olova swinga fikeleriwa kuva swifikeleriwa swilaveko swohambana hambana swa matirhiselo.
Switirhisiwa Swo Tiyile: Eka switirhisiwa swa extrusion - grade, yitala kutirhisiwa ku endla tiphayiphi to tiya, ti rigid corrugated boards, ti inlets ta mati ya mpfula, na ti rigid profiles to hambana hambana. Eka switirhisiwa swa injection - grade, yinga humelerisa swiphemu swa michini na switirhisiwa swin’wana.
Tinsimu Tin’wana: Eka indasitiri ya tintambhu na tikhebulu, yitirhisiwa ku endla tiphayiphi to sirhelela tikhebulu na ti insulating sheaths. Hikwalaho ka swivumbeko swa yona swa kahle swa insulation xikan’we naku lwisana na corrosion, yi tiyisisa vuhlayiseki na ku tshamiseka ka vuhundzisi bya gezi. Yinga tlhela yitirhisiwa ku endla switirhisiwa swin’wana swo paka leswi lavaka matimba yokarhi xikan’we naku lwisana na maxelo, kufana na ti films to paka.

Switsundzuxo swa ku Endliwa ka Swilo

Ku Lawula Mahiselo: . PVC S - 1000 yiva na vuxiyaxiya swinene eka mahiselo hinkarhi waku lulamisiwa. Mahiselo yale henhla swinene yanga endla leswaku kuva na ku bola hiku olova, leswi endlaka leswaku kuva na timhaka ta khwalithi tofana na ti bubbles xikan’we naku cinca ka muhlovo. Hi hala tlhelo, loko mahiselo yari ehansi swinene, nchumu lowu wuta tiya naswona wuta tshoveka, leswinga endla leswaku switika ku lulamisa. Xikombiso, hinkarhi wa injection molding process, mahiselo ya barrel yafanele ku lawuriwa kahle eka ndzhawu leyi faneleke kutiyisisa ku khuluka xikan’we nakufana ka PVC melt.

Matirhiselo ya Swiengeteri: . Ku antswisa matirhelo ya vuhumelerisi na khwalithi ya swikumiwa, swiengeteri swohambana hambana, swofana na stabilizers, lubricants, na plasticizers, hi ntolovelo swa laveka. Ku hlawuriwa na mpimo wa swiengeteri leswi swilava ku lulamisiwa hindlela leyi ringaneleke kuya hi tindlela tokarhi to lulamisa xikan’we na swilaveko swa swihumelerisiwa. Xikombiso, nhlayo ya plasticizer yi khumba hiku kongoma ku olova ka xitirhisiwa, kasi ti stabilizers titirhisiwa ku ndlandlamuxa ku tiya ka PVC hinkarhi wa ku lulamisiwa naku tirhisiwa, leswi sivelaka ku bola hikokwalaho ka swilo swofana na kuhisa na ku vonakala.
