Indlela Izinzinzisi ze-Liquid Kalium Zinc PVC Ezixazulula Ngayo Ubuhlungu Bekhanda Obubalulekile Bokukhiqiza

I-PVC isalokhu iwumsebenzi onzima ekukhiqizeni, kodwa isithende sayo se-Achilles—ukonakala kokushisa ngesikhathi sokucubungula—sekuyisikhathi eside sihlupha abakhiqizi.iziqinisi ze-PVC ze-kalium zinc eziwuketshezi: ikhambi elinamandla elibhekana nezinkinga eziqine kakhulu zezinto zokwakha ngenkathi lenza kube lula ukukhiqizwa. Ake sichaze ukuthi lesi sithako siguqula kanjani ukukhiqizwa kwe-PVC.

Imisa Ukuwohloka Kokushisa Ezindleleni Zayo​

I-PVC iqala ukonakala emazingeni okushisa aphansi afinyelela ku-160°C, ikhipha igesi ye-HCl eyingozi futhi iguqule imikhiqizo ibe buthaka noma ishintshe umbala. Izithambisi ze-kalium zinc eziwuketshezi zisebenza njengesivikelo sokuzivikela, zibambezela ukonakala ngokunciphisa i-HCl futhi zakhe ama-complexes azinzile ngeketanga le-polymer. Ngokungafani nezithambisi zensimbi eyodwa eziphela ngokushesha, inhlanganisela ye-kalium-zinc inikeza isivikelo eseluliwe—igcina i-PVC izinzile ngisho nangesikhathi sokuphuma isikhathi eside ku-180-200°C. Lokhu kusho ukuthi amaqoqo ambalwa alahliwe ngenxa yokuphuka noma ukuqhekeka, ikakhulukazi emikhiqizweni ye-thin-gauge efana namafilimu namashidi.​

Kuqeda Izingqinamba Zokucubungula​

Abakhiqizi bayazi ukukhungatheka kokuvalwa kwemigqa njalo. Izithambisi zendabuko zivame ukushiya insalela kuma-dies nama-screw, okuphoqa ukuthi kumiswe ukuhlanza njalo emahoreni angu-2-3. Nokho, amafomula e-liquid kalium zinc ane-viscosity ephansi egeleza kahle emishinini, okunciphisa ukwakheka. Umkhiqizi wepayipi elilodwa ubike ukuthi unciphisa isikhathi sokuhlanza ngo-70% ngemva kokushintsha, okwandisa umkhiqizo wansuku zonke ngo-25%. Ifomu loketshezi libuye lixubane ngokulinganayo ne-resin ye-PVC, lisuse ukuhlangana okubangela ukujiya okungalingani kumaphrofayili noma amapayipi.​

Kuthuthukisa Ukuqina Kwemikhiqizo Yokugcina​

Akukhona nje kuphela ngokukhiqiza—ukusebenza kokusetshenziswa kokugcina kubalulekile. Imikhiqizo ye-PVC ephathwe ngeiziqinisi ze-kalium zincikhombisa ukumelana okuthuthukisiwe nemisebe ye-UV kanye nomswakama, yandisa isikhathi sokuphila ekusetshenzisweni kwangaphandle njengamafreyimu amafasitela noma amapayipi engadini. Emikhiqizweni eguquguqukayo efana nama-gasket noma amapayipi ezokwelapha, isiqinisi sigcina ukuqina ngokuhamba kwesikhathi, sivimbele ukuqina okuholela ekuvuza noma ukwehluleka. Ukuhlola kukhombisa ukuthi le mikhiqizo igcina amandla ayo okudonsa angu-90% ngemva kwamahora angu-500 okuguga okusheshayo, idlula lawo enziwe ngezithasiselo ezivamile.​

Ihlangabezana nezindinganiso zokuphepha eziqinile​

Ingcindezi yokulawula iyanda ukuze kutholakale izithasiselo ze-PVC eziphephile, ikakhulukazi emikhiqizweni yokuxhumana nokudla noma yezinga lezokwelapha. Izithasiselo ze-liquid kalium zinc zihlola wonke amabhokisi: azinazo izinsimbi ezisindayo njenge-lead noma i-cadmium, futhi izinga lazo eliphansi lokufuduka lizigcina zihambisana nemithethonqubo ye-FDA kanye ne-EU 10/2011. Ngokungafani nezinye izithasiselo eziphilayo ezikhipha amakhemikhali, le fomula ihlala ikhiyiwe ku-polymer matrix—ibalulekile ekusetshenzisweni okufana nokupakisha ukudla noma amathoyizi ezingane.​

Izindleko Ezingabizi Ngaphandle Kokuyekethisa​

Ukushintshela ezithasiselweni zekhwalithi ephezulu kuvame ukusho izindleko eziphezulu, kodwa hhayi lapha. Ama-liquid kalium zinc stabilizers adinga umthamo ongaphansi ngo-15-20% kunezinye izindlela eziqinile ukuze kufezwe imiphumela efanayo, kuncishiswe izindleko zezinto zokusetshenziswa. Ukusebenza kahle kwawo kunciphisa nokusetshenziswa kwamandla: ukucubungula okushelelayo kunciphisa amazinga okushisa okukhipha ngo-5-10°C, kuncishiswe izindleko zikagesi. Kubakhiqizi abancane kuya kwabaphakathi, lokhu konga kuhlangana ngokushesha—ngokuvamile kubuyisela izindleko zokushintsha zingakapheli izinyanga ezingu-3-4.​

Umyalezo ucacile: iziqinisi ze-liquid kalium zinc azilungisi nje izinkinga ze-PVC—zichaza kabusha okungenzeka. Ngokuhlanganisa ukuvikelwa kokushisa, ukusebenza kahle kokucubungula, kanye nokuphepha, ziba yisinqumo esikhethwa ngabakhiqizi abenqaba ukudela ikhwalithi ngenxa yezindleko. Emakethe lapho ukuthembeka nokuthobela imithetho kungaxoxiswana ngakho, lesi sithasiselo asiyona nje intuthuko—kuyisidingo.​
