Indlela I-Liquid Kalium Zinc PVC Stabilizers Exazulula Ngayo Ikhanda Elibucayi Lokukhiqiza

I-PVC isewumsebenzi onzima ekukhiqizeni, kodwa isithende sayo se-Achilles—ukuwohloka okushisayo ngesikhathi sokucubungula—sekuyisikhathi eside kuhlupha abakhiqizi. Ngenaliquid kalium zinc PVC stabilizers: isixazululo esiguqukayo esibhekana nezinkinga zentokozo ezinenkani kakhulu ngenkathi kulungiswa ukukhiqizwa. Ake sihlukanise ukuthi lesi sengezo siwuguqula kanjani ukukhiqizwa kwe-PVC

Imisa Ukuwohloka Kwezishisayo Emathrekhi Ayo

I-PVC iqala ukwehla emazingeni okushisa afinyelela ku-160°C, ikhiphe igesi ye-HCl eyingozi futhi imikhiqizo iphendule ibe brittle noma ishintshe umbala. I-liquid kalium zinc stabilizers isebenza njengesihlangu sokuzivikela, ibambezela ukucekelwa phansi ngokwenza i-HCl ibe lula futhi yenze izakhiwo ezizinzile ngeketango le-polymer. Ngokungafani nezinzinzisi zensimbi eyodwa ezicwebezelayo ngokushesha, inhlanganisela yekalium-zinc iletha ukuvikeleka okunwetshiwe—igcina i-PVC izinzile ngisho nangesikhathi sokukhipha isikhathi eside sigijima ku-180-200°C. Lokhu kusho amaqoqo ambalwa anqatshiwe ngenxa yokuphuzi noma ukuqhekeka, ikakhulukazi emikhiqizweni yegeji encane njengamafilimu namashidi.

Iqeda Ukucubungula Amabhodlela

Abakhiqizi bayakwazi ukukhungatheka kokuvalwa kwelayini okuvamile. Iziqinisi zendabuko zivame ukushiya izinsalela kuma-dies and screws, ziphoqa izitobhi zokuhlanza njalo emahoreni angu-2-3. Amafomula e-liquid kalium zinc, nokho, ane-viscosity ephansi egeleza kahle kumishini, enciphisa ukunqwabelana. Umkhiqizi wamapayipi oyedwa ubike ukuthi isikhathi sokuhlanza sisika ngo-70% ngemva kokushintsha, okwandisa ukuphuma kwansuku zonke ngama-25%. Ifomu eliwuketshezi liphinde lixubane ngokulinganayo ne-PVC resin, lisuse ukunqwabelana okubangela ukushuba okungalingani kumaphrofayili noma amapayipi.

Ithuthukisa Ukuqina Emikhiqizweni Yokugcina

Akukhona nje mayelana nokukhiqiza—ukusebenza kokusetshenziswa kokugcina nakho kubalulekile. Imikhiqizo ye-PVC ephathwa ngayoi-kalium zinc stabilizersbonisa ukumelana okuthuthukisiwe emisebeni ye-UV kanye nomswakama, ukwelula ubude bempilo ezinhlelweni zangaphandle ezifana namafreyimu ewindi noma amapayipi angadi. Emikhiqizweni eguquguqukayo njengama-gaskets noma ishubhu yezokwelapha, isizinzisi sigcina ukunwebeka ngokuhamba kwesikhathi, sivimbela ukuqina okuholela ekuvuzeni noma ekuhlulekeni. Ukuhlola kubonisa ukuthi le mikhiqizo igcina u-90% wamandla ayo aqinile ngemva kwamahora angu-500 okuguga okusheshayo, isebenza kahle kakhulu kunaleyo eyenziwe ngezithasiselo ezivamile.

Ihlangabezana Namazinga Okuphepha Aqinile

Ingcindezi yokulawula iyakhula ezithasiselweni ze-PVC eziphephile, ikakhulukazi emikhiqizweni yokuxhumana nokudla noma yezinga lezokwelapha. Izinzinzisi ze-kalium zinc eziwuketshezi zihlola wonke amabhokisi: azinazo izinsimbi ezinzima njengomthofu noma i-cadmium, futhi izinga lazo lokufuduka eliphansi lizigcina zithobela imithetho ye-FDA kanye ne-EU 10/2011. Ngokungafani namanye ama-organic stabilizers avuzayo amakhemikhali, le fomula ihlala ivaliwe ku-polymer matrix-ibaluleke kakhulu ekusebenzeni okufana nokupakishwa kokudla noma amathoyizi ezingane.

Ingabizi Ngaphandle Kokuyekethisa

Ukushintshela kuzithasiselo ze-premium ngokuvamile kusho izindleko eziphakeme, kodwa hhayi lapha. I-liquid kalium zinc stabilizers idinga umthamo ongaphansi ngo-15-20% kunezinye izindlela eziqinile ukuze kuzuzwe imiphumela efanayo, ukusika izindleko zempahla eluhlaza. Ukusebenza kahle kwazo futhi kunciphisa ukusetshenziswa kwamandla: ukucutshungulwa okushelelayo kwehlisa amazinga okushisa e-extrusion ngo-5-10°C, kunciphisa izikweletu zezinsiza. Kubakhiqizi abancane kuya kwabamaphakathi, lokhu konga kuyanda ngokushesha—ngokuvamile kubuyisela izindleko zokushintsha phakathi nezinyanga ezingu-3-4.

Umlayezo ucacile: izizinzisi ze-kalium zinc eziwuketshezi azigcini nje ngokulungisa izinkinga ze-PVC—zichaza kabusha lokho okungenzeka. Ngokuhlanganisa ukuvikela okushisayo, ukusebenza kahle kokucubungula, nokuphepha, sekuyinto ehamba phambili kubakhiqizi abenqaba ukudela ikhwalithi ngezindleko. Emakethe lapho ukwethembeka nokuthobela kungaxoxiswana khona, lesi sengezo asikona nje ukuthuthukisa—kuyisidingo.

I-TOPJOY ChemicalInkampani ibilokhu izibophezele ocwaningweni, ekuthuthukisweni, nasekukhiqizweni kwemikhiqizo yokuqiniswa kwe-PVC esebenza kahle kakhulu. Ithimba lochwepheshe le-R&D le-Topjoy Chemical Company liqhubeka nokuqamba izinto ezintsha, lithuthukisa ukwakheka kwemikhiqizo ngokwezidingo zemakethe kanye namathrendi okuthuthukisa imboni, futhi linikeza izixazululo ezingcono zamabhizinisi okukhiqiza. Uma ufuna ukufunda ulwazi olwengeziwe mayelana nezinzinzisi ze-PVC, wamukelekile ukusithinta nganoma yisiphi isikhathi!
