Ama-PVC Resins ahlukaniswa nge-K-Value yawo, inkomba yesisindo samangqamuzana kanye nezinga le-polymerization.
• I-K70-75 iyinhlaka yenani lika-K ephezulu enikeza izici ezingcono kakhulu zokusebenza kodwa okunzima kakhulu ukuzisebenzisa.Badinga i-plasticizer eyengeziwe ukuze kube nokuthamba okufanayo.Ukusebenza okuphezulu Ukufakwa kwekhebula ku-Suspension resin kanye nama-coatings aqinile amabhande e-Conveyor, i-Industrial Flooring nezinye izinhlelo zokusebenza eziphezulu ezifanayo ku-Namathisela grade ezinye izinhlelo zokusebenza ezidumile.Ibiza kakhulu.
• I-K65-68 iyinhlaka yenani lika-K emaphakathi okuyizona ezidume kakhulu.Banokulinganisela okuhle kwezakhiwo zeMechanical kanye nokucutshungulwa.I-UPVC (I-PVC Engapulasitiki noma Eqinile) yenziwe ngamamaki angenazimbotshana kuyilapho Izicelo Zepulasitiki zenziwe kangcono kakhulu ngamamaki ambobo kakhulu.Kuningi okukhethayo kwebanga njengoba kubhekelela Iningi lezicelo ze-PVC.Ngenxa yomthamo wawo omkhulu lo mndeni wama-resin we-PVC unenani eliphansi kakhulu.
• I-K58-60 ububanzi benani le-K eliphansi.Izakhiwo zemishini ziphansi kakhulu, kodwa ukucubungula kulula kakhulu.Eziningi okunzima ukucubungula izinhlelo zokusebenza ezifana nokubumba umjovo, ukubumba i-blow kanye nefilimu yokupakisha EseKhalenda Ecacile zenziwe kusukela kububanzi benani eliphansi lika-K.Izintengo ziphakeme kune-Medium K Value Resins.
• I-K50-55 yizinhlaka ezikhethekile ezenzelwe ezinye izinhlelo zokusebenza ezinzima.Okuthakazelisayo ama-Battery Separator Resins kanye nama-Blending resins asetshenziswa kanye ne-Namathisela I-resin Yebanga ukuze kwehliswe izindleko.Ukucubungula kulula kakhulu.
Njengoba i-PVC ingu-56% Chlorine, ingenye yamaPolymers ambalwa azicisha ngokwawo, njengoba i-Chlorine iyi-Flame inhibitor enamandla.
Liyini inani le-K ku-PVC?

Iyini i-k67 PVC resin?
I-PVC Resin Virgin (K -67), i-PVC evame ukufushaniswa, iyi-polymer yesithathu ekhiqizwa kabanzi, ngemuva kwe-polyethylene ne-polypropylene.Ifomu eliqinile le-PVC lisetshenziselwa ukwakhiwa kwamapayipi nasezinhlelweni zephrofayili njengeminyango namafasitela.
Iyini i-PVC resin?
I-Poly Vinyl Chloride Resin noma i-PVC Resin njengoba ivame ukubizwa kanjalo, i-thermoplastic Resin engathanjiswa ekushisiseni kabusha.Itemu elivamile lale polymer yempahla lithi Vinyl.Ngokuvamile etholakala ngesimo sempushana, ama-PVC granules amelana kakhulu ne-oxidisation kanye nokuwohloka okubangelwa ukusabela komkhathi.
Iyini inani lika-K?
I-K-value imane iyishosha elifushane le-thermal conductivity.I-Thermal conductivity, n: isilinganiso sesikhathi sokushisa kwesimo esingaguquki esigeleza endaweni yeyunithi yento elinganayo edalwe iyunithi yezinga lokushisa eliya endaweni eqondile kuleyo ndawo yeyunithi.
Ubala kanjani inani lika-k?
Zingabalwa njenge-1 / (isamba sokuphikiswa kwezingqimba ezahlukahlukene ze-elementi (amanani aso we-R) + ukumelana kwezindawo zangaphakathi nezangaphandle zesici).
Ingabe akhona amamaki ahlukene e-PVC?
Kunezinhlobo ezimbili ezijwayelekile zamapayipi e-PVC - ishejuli ye-PVC engama-40 kanye neshejuli yama-PVC angama-80.Isheduli 40 ye-PVC ivamise ukuba mhlophe ngombala futhi ishejuli engu-80 ivamise ukuba mpunga obumnyama (ingase itholakale nakweminye imibala).Nokho, umehluko wabo obaluleke kakhulu usekuklanyweni kwabo.Ipayipi leSheduli 80 lakhiwe ngodonga olukhulu.
Isetshenziselwa ini i-UPVC?
I-UPVC, eyaziwa nangokuthi i-Unplasticized Polyvinyl Chloride, iyimpahla yokwakha engalungiswa kahle esetshenziswa esikhundleni sokhuni olupendiwe, ikakhulukazi ozimele namafasitela lapho kufakwa ukucwebezela okuphindwe kabili ezakhiweni ezintsha, noma ukufaka esikhundleni samafasitela amadala acwebezelayo.
Ubala kanjani inani lika-k?
Ukuze ubale I-K-Value yokwahlukanisa, vele uhlukanise ukujiya (ngamayintshi) Nge-R-Value.
Liyini inani lika-K?
I-K-value imane iyishosha elifushane le-thermal conductivity.I-Thermal conductivity, n: isilinganiso sesikhathi sokushisa kwesimo esingaguquki esigeleza endaweni yeyunithi yento elinganayo edalwe iyunithi yezinga lokushisa eliya endaweni eqondile kuleyo ndawo yeyunithi.Le ncazelo ayiyona inkimbinkimbi ngempela.
Iyini i-K ku-viscosity?
Inani le-K (i-viscosity), ipharamitha yokuqina esondelene kakhulu ne-viscosity yangaphakathi, evame ukuchazwa ngezindlela ezihluke kancane ezimbonini ezihlukene ukuze kuvezwe isilinganiso esisuselwe ku-viscosity yezibalo ze-molecular mass ye-polymeric material esetshenziselwa ikakhulukazi i-PVC.
Ithini ifomula yamakhemikhali ye-PVC?
I-PVC yi-Polyvinyl Chloride.Lona upulasitiki onale fomula yamakhemikhali elandelayo: CH2=CHCl (bheka isithombe kwesokudla).Ipulasitiki imboza izinhlobo eziningi zemikhiqizo ye-polymerization yokwenziwa noma i-semi-synthetic (okungukuthi ama-molecule e-carbon-based "organic" molecule) okuyigama elibhekisela eqinisweni lokuthi ku-semi-liquid yawo...
Iyini i-chemical reaction ye-PVC?
I-PVC yenziwa kusetshenziswa inqubo ebizwa nge-addition polymerization.Lokhu kusabela kuvula amabhondi aphindwe kabili ku-vinyl chloride monomer (VCM) okuvumela ama-molecule angomakhelwane ukuthi ahlangane enze ama-molecule amaketango amade.nC2H3Cl = (C2H3Cl)n vinyl chloride monomer = polyvinylchloride
Yiziphi izakhiwo ezibonakalayo ze-PVC?
Izakhiwo zomzimba nezemishini: I-PVC iyi-polymer e-atactic ngakho-ke ayinakho ukristalu.Kodwa-ke, ngezinye izikhathi kwenzeka ukuthi, endaweni, ngaphezu kwezingxenye zamaketanga amafushane, i-PVC i-sydiotactic futhi ingathatha isigaba se-crystalline, kodwa ukuphuka kwe-shear kwephesenti akulokothi kudlule i-10 kuya ku-15%.Ukuminyana kwe-PVC ngu-1.38 g/cm3.
