Indlela i-Liquid Kalium Zinc PVC Stabilizers eSombulula ngayo iintloko eziBalulekileyo zeMveliso

I-PVC ihlala ilihashe ekuveliseni, kodwa isithende sayo se-Achilles-i-thermal degradation ngexesha lokucubungula-kudala ihlupha abavelisi. Ngenaulwelo kalium zinc PVC izinzisi: isisombululo esiguqukayo esijongana neyona miba inenkani yemathiriyeli ngelixa uhlengahlengisa imveliso. Makhe sijonge ukuba olu songezo luyitshintsha njani imveliso yePVC

Imisa ukuqhekeka kweThermal kwiingoma zayo

I-PVC iqala ukuthotywa kumaqondo obushushu asezantsi ukuya kwi-160°C, ikhupha irhasi enobungozi yeHCl kunye neemveliso ezijikajikayo zibe brittle okanye zibe nombala. I-liquid kalium zinc stabilizers zisebenza njengekhaka elikhuselayo, ukulibazisa ukuthotywa ngokungathathi hlangothi kweHCl kunye nokwenza ii-complexes ezizinzileyo kunye nekhonkco le-polymer. Ngokungafaniyo ne-single-metal stabilizers ekhupha ngokukhawuleza, i-kalium-zinc combo ihambisa ukhuseleko olongezelelweyo-ukugcina i-PVC izinzile nangona ixesha elide liqhuba kwi-180-200 ° C. Oku kuthetha ukuba iibhetshi ezimbalwa ezikhatywayo ngenxa yokuba tyheli okanye ukuqhekeka, ngakumbi kwiimveliso zegeyiji ecekethekileyo efana neefilimu kunye namaphepha.

Iphelisa iProcessing Bottlenecks

Abavelisi bayayazi ingxaki yokuvalwa kwemigca rhoqo. Izinzisi zemveli zihlala zishiya intsalela kwi-dies and screws, ukunyanzelisa ukumisa ukucoca rhoqo kwiiyure ezingama-2-3. Iifomyula ze-kalium zinc, nangona kunjalo, zine-viscosity ephantsi ehamba kakuhle ngokusebenzisa izixhobo, ukunciphisa ukwakhiwa. Omnye umenzi wombhobho wabika ukusika ixesha lokucoca nge-70% emva kokutshintsha, ukwandisa imveliso yemihla ngemihla ngama-25%. Ifom yolwelo ikwaxuba ngokulinganayo kunye ne-PVC resin, isusa ukuhlangana okubangela ukutyeba okungalinganiyo kwiiprofayili okanye kwimibhobho.

Yongeza uZinzo kwiiMveliso zokugqibela

Ayisiyiyo imveliso kuphela-imicimbi yokusetyenziswa kokuphela nayo. Iimveliso zePVC ziphathwa ngei-kalium zinc stabilizersbonisa ukuxhathisa okuphuculweyo kwimitha ye-UV kunye nokufuma, ukwandisa ixesha lokuphila kwizicelo zangaphandle njengezakhelo zefestile okanye imibhobho yegadi. Kwiimveliso eziguquguqukayo ezifana ne-gaskets okanye i-tubing yonyango, i-stabilizer igcina i-elasticity ngokuhamba kwexesha, ukuthintela ukuqina okukhokelela ekuvuzeni okanye ukungaphumeleli. Uvavanyo lubonisa ukuba ezi mveliso zigcina i-90% yamandla azo okuqina emva kweeyure ezingama-500 zokuguga okukhawulezileyo, zisebenza kakuhle ngakumbi ezo zenziwe ngezongezo eziqhelekileyo.

Idibana neMigangatho eMiselweyo yoKhuseleko

Uxinzelelo lolawulo luyanyuka kwizinto ezikhuselekileyo ze-PVC, ngakumbi kwiimveliso zokutya okanye zodidi lwezonyango. I-liquid kalium zinc stabilizers jonga zonke iibhokisi: azinazo iintsimbi ezinzima njengelothe okanye i-cadmium, kwaye izinga lokufuduka kwazo eliphantsi lizigcina zihambelana ne-FDA kunye ne-EU 10/2011 imigaqo. Ngokungafaniyo nezinye i-organic stabilizers ezikhupha iikhemikhali, le fomyula ihlala itshixiwe kwi-polymer matrix-ibaluleke kakhulu kwizicelo ezifana nokupakishwa kokutya okanye iithoyi zabantwana.

Ixabiso Elisebenzayo Ngaphandle Kokuthobela

Ukutshintshela kwizongezo zeprimiyamu kuhlala kuthetha iindleko eziphezulu, kodwa hayi apha. I-liquid kalium zinc stabilizers ifuna i-15-20% idosi engaphantsi kuneendlela eziqinileyo zokuphumeza iziphumo ezifanayo, ukusika iindleko zezinto eziluhlaza. Ukusebenza kwabo kukwanciphisa ukusetyenziswa kwamandla: ukusetyenzwa kakuhle kwehlisa amaqondo obushushu aphuma kwi-5-10 ° C, ukucheba amatyala oncedo. Kubavelisi abancinci ukuya kwabaphakathi, olu londolozo longeza ngokukhawuleza-kaninzi lubuyisela iindleko zokutshintsha kwiinyanga ezi-3-4.

Umyalezo ucacile: izizinzi ze-kalium zinc azilungisi nje iingxaki ze-PVC-zichaza kwakhona into enokwenzeka. Ngokudibanisa ukhuseleko lwe-thermal, ukusebenza kakuhle, kunye nokhuseleko, baye baba lelona khetho lokuzikhethela kubavelisi abala ukuncama umgangatho ngexabiso. Kwimarike apho ukuthembeka kunye nokuthotyelwa kungaxoxiswana, olu songezo alukho nje ukuphuculwa-yinto eyimfuneko.
