Indlela i-Liquid Kalium Zinc PVC Stabilizers ezisombulula ngayo iintloko ezibuhlungu zemveliso

I-PVC isasebenza nzima kakhulu kwimveliso, kodwa isithende sayo se-Achilles—ukonakala kobushushu ngexesha lokucubungula—kusoloko kukhathaza abavelisi.iziqinisi ze-PVC ze-kalium zinc ezingamanzi: isisombululo esitshintshatshintshayo esijongana neengxaki ezinzima kakhulu zezinto ezibonakalayo ngelixa silungisa imveliso. Makhe sihlalutye indlela esi songezo esiguqula ngayo imveliso yePVC.

Iyeka Ukuphazamiseka Kobushushu Kwimikhondo Yayo

I-PVC iqala ukonakala kumaqondo obushushu aphantsi njenge-160°C, ikhupha igesi ye-HCl eyingozi kwaye iguqule iimveliso zibe buthathaka okanye zibe nombala ohlukileyo. Iziqinisi ze-kalium zinc ezingamanzi zisebenza njengesikhuselo sokuzikhusela, zibambezela ukonakala ngokunciphisa i-HCl kwaye zenze ii-complexes ezizinzileyo ngetsheyini ye-polymer. Ngokungafaniyo neziqinisi zesinyithi esinye eziphela ngokukhawuleza, i-kalium-zinc combo inika ukhuseleko olongezelelweyo—igcina i-PVC izinzile nangona ixesha elide lokukhupha kwi-extrusion liqhuba kwi-180-200°C. Oku kuthetha ukuba iibhetshi ezimbalwa ezilahliweyo ngenxa yokutyheli okanye ukuqhekeka, ingakumbi kwiimveliso ezi-thin-gauge ezifana neefilimu kunye namaphepha.​

Iphelisa iingxaki zokucubungula

Abavelisi bayayazi ingxaki yokuvalwa rhoqo kwemigca. Iziqinisi zemveli zihlala zishiya intsalela kwiidayi kunye nezikrufu, nto leyo enyanzelisa ukuba kumiswe ukucoca rhoqo emva kweeyure ezi-2-3. Nangona kunjalo, iifomyula ze-liquid kalium zinc zine-viscosity ephantsi ehamba kakuhle kwizixhobo, nto leyo enciphisa ukwakheka. Omnye umenzi wemibhobho uxele ukuba unciphisa ixesha lokucoca nge-70% emva kokutshintsha, nto leyo enyusa imveliso yemihla ngemihla nge-25%. Le fomyula ikwaxubana ngokulinganayo ne-PVC resin, isusa ukuxinana okubangela ukungalingani kobukhulu kwiiprofayili okanye imibhobho.

Iphucula Ukuqina Kweemveliso Zokugqibela​

Ayisiyonto nje yokuvelisa—ukusebenza kokusetyenziswa kokugqibela kubalulekile. Iimveliso zePVC eziphathwa ngeiziqinisi ze-kalium zinczibonisa ukumelana okuphuculweyo kwimitha ye-UV kunye nokufuma, nto leyo eyandisa ubomi bayo kwiindawo zangaphandle ezifana neefreyimu zeefestile okanye iipayipi zegadi. Kwiimveliso eziguquguqukayo ezifana neegaskets okanye iityhubhu zonyango, isizinzisi sigcina ukuthamba ngokuhamba kwexesha, sithintela ukuqina okukhokelela ekuvuthweni okanye ekusileleni. Uvavanyo lubonisa ukuba ezi mveliso zigcina i-90% yamandla azo okutsalwa emva kweeyure ezingama-500 zokwaluphala ngokukhawuleza, ziphumelela ngaphezu kwezo zenziwe ngezithako zesiqhelo.

Ihlangabezana neMigangatho yoKhuseleko eQondileyo

Uxinzelelo olulawulayo luyanda kwi-PVC ezongeziweyo ezikhuselekileyo, ngakumbi kwiimveliso ezidityaniswe nokutya okanye ezikumgangatho wezonyango. Iziqinisi ze-liquid kalium zinc zijonga zonke iibhokisi: azinazo iintsimbi ezinzima ezifana ne-lead okanye i-cadmium, kwaye izinga lazo lokufuduka eliphantsi lizigcina zihambelana nemigaqo ye-FDA kunye ne-EU 10/2011. Ngokungafaniyo nezinye iziqinisi ze-organic ezikhupha iikhemikhali, le fomula ihlala itshixiwe kwi-polymer matrix—ibaluleke kakhulu kwizicelo ezifana nokupakishwa kokutya okanye izinto zokudlala zabantwana.​

Ixabiso Eliphantsi Ngaphandle Kokuyekelela​

Ukutshintshela kwizongezo zeprimiyamu kudla ngokuthetha iindleko eziphezulu, kodwa hayi apha. Iziqinisi ze-liquid kalium zinc zifuna idosi engaphantsi nge-15-20% kunezinye iindlela eziqinileyo ukuze kufezekiswe iziphumo ezifanayo, zinciphisa iindleko zezinto eziluhlaza. Ukusebenza kwazo kakuhle kunciphisa nokusetyenziswa kwamandla: ukucubungula okuthambileyo kunciphisa amaqondo obushushu okukhupha izinto nge-5-10°C, kunciphisa iindleko zeenkonzo. Kubavelisi abancinci ukuya kwabaphakathi, ezi mali zongeyo ziyongeza ngokukhawuleza—zihlala zibuyisela iindleko zokutshintsha ngaphakathi kweenyanga ezi-3-4.​

Umyalezo ucacile: iziqinisi ze-liquid kalium zinc azilungisi nje iingxaki ze-PVC—zichaza kwakhona oko kunokwenzeka. Ngokudibanisa ukhuseleko lobushushu, ukusebenza kakuhle kokucubungula, kunye nokhuseleko, ziba lukhetho olukhethwa ngabavelisi abangavumiyo ukuncama umgangatho ngenxa yexabiso. Kwimarike apho ukuthembeka kunye nokuthobela imithetho kungaxoxiswananga, esi sihlomelo asikokuphucula nje kuphela—siyimfuneko.​
