Ukudipha iimveliso zesixhobo zonyango: into ekufuneka uyazi

Xa kuziwa kwimveliso ye-rubber emulsion yokudipha, uchungechunge lwamanyathelo enkqubo kufuneka lugqitywe ukuze kuqinisekiswe ukubunjwa okufanelekileyo, i-vulcanization kunye nonyango lomhlaba ukuhlangabezana neemfuno zabathengi kwisicelo sokugqibela. Ukubumba idiphu kunokuvelisa izixhobo zonyango ezomeleleyo zeemilo ezahlukeneyo, ubungakanani kunye nobukhulu beendonga, kubandakanywa izigqubuthelo zeprobe, izivuno, izitywina zentamo, iiglavu zotyando, iibhaluni zentliziyo kunye namanye amalungu awodwa. Irabha yendalo inokomelela okugqwesileyo kunye nokomelela okuphezulu, kodwa ikwaphethe iprotheyini enokubangela ukuguquguquka komzimba womntu. Ngokwahlukileyo, i-synthetic neoprene kunye ne-synthetic polyisoprene ayibangeli i-allergies. I-Neoprene inokumelana novavanyo lwezinto ezininzi; iyamelana nomlilo, ioli (ephakathi), imozulu, i-ozone yokuqhekeka, i-abrasion kunye ne-flex cracking, i-alkali kunye nokumelana ne-asidi. Ngokumalunga nokuziva kunye nokuguquguquka, i-polyisoprene ithatha indawo esondeleyo yerabha yendalo kwaye inokumelana nemozulu engcono kune-latex yerabha yendalo. Nangona kunjalo, i-polyisoprene incama amandla athile, ukuxhathisa ukukrazula, kunye neseti yoxinzelelo. Igama elithi "impregnation" linxulumene nokusebenza ngendlela yokukhulelwa. Enyanisweni, njengoko ulandelelwano luqhutywa, itafile iya kubhaptiza kwizinto eziphathekayo. Kubaluleke kakhulu ukuqinisekisa ukuba ukuqulunqwa kwerabha kuhambelana nezikhokelo zesixhobo sonyango kunye neemfuno ze-FDA. Inkqubo yokufakwa kwe-impregnation inokubonakaliswa ngokulandelelana kokuguqulwa: i-rubber iguqulwa ukusuka kwi-liquid ibe yinto eqinile, kwaye emva koko iguqulwe ikhemikhali ibe yinethiwekhi ye-molecular vulcanized. Okubaluleke ngakumbi, inkqubo yeekhemikhali iguqula irabha ukusuka kwifilimu ebuthathaka kakhulu ibe yinethiwekhi yeemolekyuli ezinokolulwa kwaye zikhubazeke, kwaye zibuyele kubume bayo bokuqala. Inkqubo yokuqinisa ayisoloko iyimfuneko kuzo zonke iinkqubo "zokudipha", kodwa ibalulekile kulandelelwano lwethu lokuqhuba. Irabha inokutshintshwa isuke kulwelo iye ekubeni qinileyo ngokomiswa ngomoya, kodwa oku kuthatha ixesha elide. Ezinye iindawo ezinodonga olubhityileyo ziveliswa ngolu hlobo. Inkqubo yokuqinisa isebenzisa iikhemikhali ukunyanzela le meko yomzimba ukuba itshintshe. I-coagulant ngumxube okanye isisombululo setyuwa, i-surfactant, i-thickener, kunye ne-arhente yokukhulula kwi-solvent (ngokuqhelekileyo amanzi). Kwezinye iinkqubo, utywala bunokusetyenziswa njengesinyibilikisi. Utywala buba ngumphunga ngokukhawuleza kwaye kukho intsalela encinane. Amanye ama-coagulants asekelwe emanzini afuna uncedo lwe-oven okanye ezinye iindlela zokomisa i-coagulant. Inxalenye ephambili ye-coagulant ityuwa (i-calcium nitrate), into engabizi kakhulu ebonelela ngokufana kwe-coagulation kwifom efakwe. I-surfactant isetyenziselwa ukumanzisa ifom edibeneyo kwaye iqinisekise ukuba i-coagulant egudileyo, i-coagulant ifakwe kwifom. I-agent ekhuphayo, efana ne-calcium carbonate, isetyenziswe kwi-coagulant formulation ukunceda ukususa inxalenye yerabha ephilisiweyo kwifom editshiweyo. Isitshixo ekusebenzeni kwe-coagulant kubandakanya ukugqoka okufanayo, ukukhuphuka ngokukhawuleza, ukushisa kwezinto eziphathekayo, ukungena kunye nesantya sokubuyisela, kunye nokuguqulwa lula okanye ukugcinwa kwe-calcium concentration. Eli linqanaba apho irabha itshintsha ukusuka kulwelo ukuya kokuqinileyo. I-agent yekhemikhali ekhuthaza i-coagulation, i-coagulant, ngoku isetyenziswe kwifom edibeneyo kwaye yomile. Ifom "ibekwe", okanye ifakwe kwitanki yerabha engamanzi. Xa irabha idibana nomzimba kunye ne-coagulant, i-calcium ekwi-coagulant iya kubangela ukuba irabha ingazinzi kwaye itshintshe ukusuka kulwelo ukuya kwisiqina. Ixesha elide imodeli intywiliselwa, udonga lukhulu. Le mpendulo yeekhemikhali iya kuqhubeka de yonke i-calcium idliwe kwi-coagulant. Isitshixo kwi-latex dipping ibandakanya isantya sokungena kunye nokuphuma, ukushisa kwe-latex, ukufana kwe-coagulant coagulant, kunye nokulawulwa kwe-pH, i-viscosity kunye nomxholo opheleleyo we-rubber. Inkqubo yokucoca lelona nqanaba lisebenzayo lokususa imichiza engafunekiyo esekwe emanzini kwimveliso yokugqibela. Elona xesha lilungileyo lokususa izinto ezingafunekiyo kwifilimu efakiweyo i-leaching ngaphambi kokunyanga. Amacandelo ezinto eziphambili ziquka i-coagulant (calcium nitrate) kunye nerubha (yendalo (NR); neoprene (CR); i-polyisoporene (IR); i-nitrile (NBR)). I-leaching engonelanga inokukhokelela "kwi-sweat", iifilimu ezincangathi kwimveliso egqityiweyo, kunye nomngcipheko okhulayo wokungaphumeleli kokubambelela kunye nokuphendula komzimba. Isitshixo ekusebenzeni kwe-leaching kubandakanya umgangatho wamanzi, ubushushu bamanzi, ixesha lokuhlala kunye nokuhamba kwamanzi. Eli nyathelo ngumsebenzi onamanyathelo amabini. Amanzi kwifilimu yerabha asusiwe, kwaye ngokuhamba kwexesha, ukushisa kwe-oven kuya kusebenzisa i-accelerator kwaye iqalise inkqubo yokunyanga okanye i-vulcanization. Xa ulungiselela ezona zakhiwo zibalaseleyo zomzimba weentlobo ezahlukeneyo zerabha, ixesha lokunyanga kunye nobushushu bonyango yeyona nto iphambili. Kukho iinketho ezininzi zokuphatha umphezulu weendawo eziditshiweyo ukuze iindawo zingabambeki. Ukhetho lubandakanya iinxalenye zomgubo, i-polyurethane yokwambathisa, i-silicone yokuhlamba, i-chlorination kunye nokuhlamba isepha. Imalunga nokuba bafuna ntoni abathengi okanye bafuna ukwenza iimveliso zabo ziphumelele. Umrhumo uyilo lwezonyango kunye nokuthunyelwa ngaphandle. Bookmark, wabelane kwaye usebenzisane neejenali zobunjineli boyilo lwezonyango oluphambili namhlanje. I-DeviceTalks yingxoxo phakathi kweenkokheli zobuchwepheshe bezonyango.
