Iyini inani le-K ku-PVC resin?

K Inani ku-PVC Resin: Iyini futhi Kungani Ibalulekile?

Kungenzeka ukuthi uke wezwa igama elithi 'K value' lisetshenziswa njalo uma kufanele ube umuntu ophathelene nenhlaka ye-PVC. Nakuba kuyini ngokunembile? Inani lika-K liwuhlelo lokulinganisa olusetshenziselwa ukuthola izinga elimaphakathi kunhlaka ye-PVC. Kuyijaji lepharamitha elibalulekile inombolo ye-Pvc resin in China ye-polymerization uma ubheka i-PVC futhi inomthelela omuhle ezicini zayo.

Izinzuzo ze-K Value

Ake sihlole izinzuzo zenani le-K ku-PVC resin imininingwane eyengeziwe. Okokuqala, idlala umsebenzi obalulekile wokubikezela izici ze-PVC. Ingasiza ekunqumeni isisindo se-molecular resin, okuthi, ngokushintsha, idlale umsebenzi obalulekile wokubikezela umshini, ukucubungula, nezici zokusetshenziswa kokugcina komkhiqizo.

Okwesibili, ihlukanisa amamaki e-PVC. Amanani ahlukene ka-K abonisa amanani ahlukene e-polymerization, ethinta ukuphathwa, ukucubungula, nokusebenza kahle mayelana ne-resin. Isibonelo, amanani aphansi ka-K anomkhuba wokuletha imikhiqizo evumelana nezimo futhi amanani aphezulu ka-K aqala imikhiqizo eqinile nenamandla kakhulu.

Ukuqamba Nokuphepha Kuvelu ye-K

Ukuqamba kabusha kuyisici esibalulekile sembonini, futhi i-PVC iyafana. Inani lika-K lidlale umsebenzi obalulekile wokuphusha embonini ngokusiza pvc-sg-1 abakhiqizi bakha imikhiqizo emisha, ethuthukisiwe. Isibonelo, ngokusebenzisa usizo lwevelu engu-K, abakhiqizi bangenza i-PVC ngezakhiwo ezifana nokuphikiswa komlilo we-electrical conductivity, kanye nesimo sezulu, phakathi kokunye.

Ukuphepha kungenye ingxenye yemboni ye-PVC inani le-K elisizile ukuba libe ngcono. Ngokubala izinga le-polymerization, pvc-k72-74 abakhiqizi bangakwazi ukubikezela ngokunembile izimfanelo ze-PVC, okubasiza ukuba banqume ukuphepha kwayo ezinhlelweni eziningi. Uma usulazi inani le-K le-PVC livumela abakhiqizi ukuthi bakhiqize imikhiqizo engase itholakale ngokufanelekile ezimbonini ezihlukahlukene, okufaka phakathi ezokwakha, ezokunakekelwa kwezempilo, ezezimoto, futhi kakhulu.

Isetshenziswa kanjani Inani le-K

Manje kuyasetshenziswa ukuthi sixoxe ngokuthi sonke sazi kanjani inani le-K value let. Inani le-K le-PVC linqunywa kusetshenziswa i-viscometer noma isistimu ye-gel permeation chromatography, ekala i-viscosity noma isisindo se-molecular eyengeziwe ye-polymer, ngokulandelanayo. Ezinye izinkampani zihlinzeka ngamavelu e-K alinganiswe ngaphambilini ngenxa yezinsalela zazo ze-PVC, okwenza inqubo yabathengi ibe lula.

Isevisi kanye nekhwalithi

Isevisi kanye nekhwalithi yizindaba ezimbili ezibalulekile ezifunwa ngabathengi ngenkathi bethenga i-PVC resin. Izinkampani ezihlinzeka ngezinhlaka ze-PVC ezinamavelu e-K zihlinzeka amakhasimende nento eyikhwalithi ezosiza ukuhlangabezana nezidingo zawo ezithile. Ukuthola ukuqonda okukude ngevelu ye-K ye-PVC resin ekhethiwe kuvame ukwenza isiqiniseko sokuthi lo mkhiqizo unikeza izimfanelo ezilindelwe kanye nokusebenza kahle.

Kuyadingeka futhi ukuqaphela ukuthi iyiphi pvc-k57-59izinkampani ezikala inani lika-K ngokunembile futhi ezinikeza amakhasimende azo isevisi ethembekile. Kuyasiza ukunciphisa kancane kancane isikhathi sokuphumula, okuyisici esibalulekile esithinta yonke imboni.

Izicelo ze-K Value ku-PVC Resin

Inani le-K linezinhlelo zokusebenza ezahlukene ngaphakathi kwemboni ye-PVC, okwenza lokhu kube abahlinzeki bepharamitha ababalulekile. Kuyasiza ukunquma izakhiwo ze-PVC resins, okubalulekile ngokusetshenziswa kwayo okuhlukile. I-PVC enamanani aphezulu we-K isetshenziselwa ukukhiqiza amapayipi, izintambo zikagesi, namaphrofayili aqinile, kuyilapho amanani aphansi e-K asetshenziselwa ukwakha ama-flooring, amamuvi, namakhasi avumelana nezimo.
