Ukuvumelanisa kweStoichiometric — Ukuphucula iiRatios zokuxuba i-A/B Component Base
Iiyunithi zeglasi ezifakela ubushushu (IG) zisebenza njengezinto ezibalulekileyo kwiimvulophu zokwakha ezisebenzisa amandla amaninzi. Ezi yunithi kufuneka zigcine ukuvalwa kwesakhiwo kunye nokusebenza kobushushu kangangeminyaka emininzi. Iimeko ezinzima zendalo zihlala zivavanya ukuqina kwazo. Imitha ye-Ultraviolet, uxinzelelo lomoya, kunye nokufuma zihlala zihlasela imiphetho yeglasi. Izakhiwo zokwenza iglasi zijongene noxinzelelo oluqhubekayo ukuphucula ukusebenza kwayo ngelixa zigcina umgangatho. Ke ngoko, ukuseka ubudlelwane bobuchwephesha obuthembekileyo kunye nenkampani ephambiliUmenzi weSealant ye-IG yeCandelo eliBini elithengiswayoKubalulekile. Ukuvalwa kwesibini okufanelekileyo kuthintela ukuwohloka kwesakhiwo kwiindlela zeglasi ezineepaneli ezininzi. Kukwathintela ukungaphumeleli kwetywina lomphetho ngokufanelekileyo. Esi sikhokelo sibanzi sihlola izinto ezibalulekileyo zokusebenza, iindlela zezixhobo, kunye namanyathelo okuqinisekisa umgangatho. Ezi zinto ziyimfuneko ukufezekisa ukuveliswa kweyunithi ye-IG engenasiphako. Ngokugxila kwi-fluid dynamics ephucukileyo, izityalo zokucubungula zinokwandisa ubomi benkonzo yeglasi yokwakha. Iiprojekthi zorhwebo zanamhlanje zifuna ukuchaneka kobunjineli obunzulu. Ngenxa yoko, abavelisi kufuneka banikeze iifomyula ezihambelanayo ezimelana nokudinwa okusingqongileyo ixesha elide. Inqanaba ngalinye lemveliso lifuna ukujongwa ngokungqongqo ukuze kususwe iimpazamo. Le ndlela yokulungiselela iqinisekisa uzinzo olufanelekileyo lwesakhiwo kulo lonke ujikelezo lwesakhiwo.
Isitywino sesibini seyunithi yeglasi ekhuselayo sifuna ulungelelwaniso oluchanekileyo lweekhemikhali ngexesha lokuveliswa. Iinkqubo ze-silicone ezinamacandelo amabini ziquka iCandelo A kunye neCandelo B. Icandelo A liqulethe i-polymer yesiseko se-siloxane. Icandelo B liphethe iphakheji ye-cross-linker kunye ne-catalyst. Izityalo ezicubungulayo kufuneka zigcine umlinganiselo ochanekileyo wobunzima okanye wevolumu phakathi kwezi zinto. Oku kufezekisa inethiwekhi ye-polymeric efanelekileyo. Ngokwesiqhelo, oomatshini bokukhupha ngokuzenzekelayo basebenzisa umlinganiselo wokuxuba wevolumu ukusuka kwi-9:1 ukuya kwi-11:1. Ukuba iCandelo B liyaphambuka kwiiparameter zomenzi, impendulo yekhemikhali ivelisa iimpawu ezingaphantsi. Umzekelo, ubungakanani be-catalyst obaneleyo bucothisa i-curing kinetics. Le ngxaki ikhokelela kwixesha elide elingena-tack kunye nemiqobo yemveliso. Ukusebenza kakuhle kwezityalo kuyehla xa ukucutshungulwa kuncipha. Ngokwahlukileyo koko, ukuxinana okugqithisileyo kweCandelo B kukhawulezisa ukucutshungulwa ngokukhawuleza kakhulu. Le mpendulo ikhawulezayo ibangela ukubuthathaka okukhulu kunye ne-modulus ephezulu. Ukungalingani okunjalo kunciphisa iiprofayili zoxinzelelo lokugqibela kwaye kunciphisa ubunzima be-Shore A. Ngenxa yoko, i-matrix ye-silicone ephilisiweyo ayinakumelana noxinzelelo olunamandla oluvela kumandla omoya. Ukusilela kwesakhiwo kunokwenzeka ukuba amalungu alahlekelwa bukuguquguquka. Ke ngoko, abaqhubi beentambo kufuneka basebenzise iindlela ezingqongqo zokulinganisa imihla ngemihla kwiimpompo zokukhupha. Kufuneka bajonge uxinzelelo lwesiseko rhoqo. Izakhiwo zanamhlanje zihlala zilandelela le milambo yokuhamba ukuze zigcine umahluko ngaphakathi kokunyamezelana okuvumelekileyo. Olu qwalaselo luthintela iimpazamo zebhetshi ezibizayo. Ukuxhasa ezi mfuno, iJunbond iyila imigca yayo yokuvala inqwaba eneempawu ezithile ze-rheological. Ezi fomyula zibonisa ukuziphatha okuhle kakhulu kokunciphisa ukusika phantsi koxinzelelo lwepompo yemizi-mveliso oluqhelekileyo. Olu hambo luqinisekisa ukuhamba kwezinto rhoqo kwimigca yeglasi yerobhothi ekhawulezayo. Abaqhubi bafumana ukusetyenziswa okugudileyo ngaphandle kokufumana ixesha lokungasebenzi komatshini. Amanqanaba okuhamba ahambelanayo anciphisa umsebenzi wezandla kunye nenkunkuma yezinto ngexesha lemijikelo yemveliso ephezulu.
Utshintsho lweFluid kunye nezithintelo zomphunga — Ukuqinisekisa ukufana ukuze kuncitshiswe iMVTR kwaye kugcinwe igesi yeArgon
Ukufikelela kumlinganiselo ochanekileyo weekhemikhali linyathelo lokuqala kuphela. Abaqhubi beentambo kufuneka baqinisekise ukuba ulwelo luhambelana ngokupheleleyo ngokuxuba iindibano zezibhamu. Ukuxuba okunganelanga kudala iindawo ezifileyo zeekhemikhali kunye nee-striations ezingaxutywanga. Ezi ziphene zisongela ngokukhawuleza ukuthembeka kwetywina lesakhiwo. Ke ngoko, iingcali zolawulo lomgangatho kufuneka zenze uvavanyo lwebhabhathane oluqhelekileyo ngaphambi kokuba imveliso iqale. Abaqhubi bakhupha isampuli ye-silicone exutyiweyo ephepheni, bayisonge, baze bayitsale. Bahlola ngokusondeleyo icandelo elingaphakathi. Naziphi na imigca emhlophe ebonakalayo okanye iipateni ezimabula zibonisa ukusasazeka kwe-catalyst okungalunganga. Esi siphumo sifuna ukulungiswa kwangoko koomatshini ukuthintela ukungaphumeleli. Iingcali kufuneka zicoce okanye zitshintshe izinto zokuxuba ezingashukumiyo ngokukhawuleza. Unyango olungalinganiyo luchaphazela ngokuthe ngqo isakhiwo se-microscopic se-elastomeric matrix. Esi siphene sinyusa i-Moisture Vapor Transmission Rate, eyaziwa ngokuba yi-MVTR. I-MVTR ephezulu ivumela umphunga wamanzi omoya ukuba udlule kwitywina lesibini. Olu mswakama lugqithisa i-desiccant spacer ephambili ngokuhamba kwexesha. Ngenxa yoko, lukhokelela ekujikeni kweyunithi yangaphakathi kwangethuba kunye nokufiphala kweglasi okungapheliyo. Ubuhle bobuhle kunye nexabiso lokukhusela ziyanyamalala ngokupheleleyo. Ngaphezu koko, isitywina sesibini esibuthathaka sivumela iigesi ezintle ezibizayo ukuba ziphume emngxunyeni. Ukugcina ukugcinwa kwegesi ephezulu ye-argon kubalulekile kwiikhowudi zamandla okwakha zanamhlanje. Izifundo ezenziwe yi-abavelisi kunye nabathengisi abaphambili be-IG sealant abanamacandelo amabiniibonisa ukuba ii-micro-voids ziyakhawulezisa ukusasazwa kwegesi. Ukuthintela le meko, iShanghai Junbond Advanced Chemicals Co., Ltd iphucula imo ye-filler ngaphakathi kweendlela zayo. Le sayensi yezinto ezibonakalayo iseka indlela egobileyo kakhulu yomswakama kunye neemolekyuli zegesi. Umqobo ophambili ugcina i-argon ivaliwe ngaphakathi kweyunithi kangangeminyaka emininzi. Le teknoloji iqinisekisa ukusebenza okuzinzileyo kobushushu kwiinzame zokwakha eziluhlaza.
I-Diagnostic Troubleshooting Matrix — Ukusombulula Iingxaki Zomgca Ukusuka Ekupholeni Okucothayo ukuya kwi-Extrusion Cavitation
Ukugcina ukuhamba kwemveliso kungaphazanyiswa kufuna ukusombulula iingxaki ngokukhawuleza kumgangatho wefektri. Ingxaki enye eqhelekileyo ibandakanya ukulibaziseka kokuphilisa okungalindelekanga, apho i-sealant ihlala inamathele iiyure ezininzi. Iingcali kufuneka ziphande ngoko nangoko izinto eziguquguqukayo zangaphandle. Ukufuma okuphantsi kwe-ambient kudla ngokucothisa i-neutral curing kinetics kakhulu. Iimolekyuli zamanzi emoyeni ziqhuba impendulo yesibini yokudibanisa. Ukongeza, kufuneka zijonge ungcoliseko lweekhemikhali okanye ukutyibilika koomatshini kwiimpompo zokulinganisa. Ukuguguleka koomatshini kunokutshintsha isantya sokondla buthule. Omnye umngeni oqhelekileyo wokusebenza kukufaka imigca okanye ukubopha kwi-nozzle ye-extrusion. Le ngxaki idla ngokuvela kuxinzelelo lwe-nozzle olungalunganga okanye isantya somxube esingalungelelaniswanga kakuhle. Ezi mpazamo zoomatshini zishiya iintsalela ezingcolileyo ecaleni komjikelezo weglasi. Abaqhubi banokususa ukubopha ngokulungisa useto loxinzelelo lwangasemva ngononophelo. Kufuneka baqinisekise ulungelelwaniso oluchanekileyo lokunqunyulwa koomatshini. Ngaphezu koko, iifektri zokuvelisa kufuneka zimisele iindlela ezingqongqo zokukhusela ukugcinwa kweendibano zezibhamu zokuxuba. Ukucoca rhoqo i-solvent kuthintela iibhloko ezicociweyo ukuba zingabikho ngaphakathi kweendlela zolwelo. Ukuvalwa okucociweyo kubangela ukunyuka okukhulu koxinzelelo kunye nomonakalo wepompo. Xa inkqubo yokuxuba ifumana ukuvalelwa komoya, idala izithuba zangaphakathi. Ezi zithuba zenza buthathaka ukubopha kwesakhiwo. Ukunceda abaprosesa beglasi,Junbond (Shanghai Junbond Advanced Chemicals Co., Ltd)Ibonelela ngezikhokelo zobugcisa ezipheleleyo. Le nkampani inika ii-curves ezixhomekeke kubushushu ukuze iphucule iifestile zokucubungula. Ezi seti zedatha ezisekelwe kwi-empirical zinceda iinjineli zigcine imveliso ezinzileyo kuzo zonke iimeko zezityalo ezitshintshayo ngexesha lonyaka. Idatha echanekileyo inciphisa ixesha lokungasebenzi ngexesha lokutshintsha kwehlobo okanye ubusika.
