Ulwelo lweRubha yeSilicone (LSR) yokuBumba iSitofu

Yintoni ukuBunjwa kweLiquid Silicone Rubber (LSR) yokuTofa?

I-injection molding ye-Liquid Silicone Rubber (LSR) yinkqubo esetyenziselwa ukuvelisa iindawo ezithambileyo, ezomeleleyo kwimiqulu ephezulu. Ngexesha lenkqubo, amacandelo amaninzi ayimfuneko: i-injector, i-metering unit, i-drum yokubonelela, i-mixer, i-nozzle, kunye ne-mold clamp, phakathi kwabanye.

Ukubunjwa kwe-injection ye-Liquid Silicone Rubber (LSR) bubuchwepheshe obuqhelekileyo obusetyenziselwa ukuveliswa kweemveliso ezahlukeneyo kwizicelo zonyango kunye nombane, phakathi kwabanye. Ukongeza kwiipropathi zangaphakathi zemathiriyeli, iiparamitha zenkqubo zibaluleke kakhulu. Ukubumba inaliti ye-LSR yinkqubo yamanyathelo amaninzi evezwayo.

Isinyathelo sokuqala kukulungiswa komxube. I-LSR idla ngokuba namacandelo amabini, i-pigment, kunye ne-additives (izigcwalisi umzekelo), ngokuxhomekeke kwiipropati ezifunwayo zemveliso yokugqibela. Kule nyathelo, izithako zomxube zi-homogenized kwaye zinokudibaniswa nenkqubo yokuzinzisa ubushushu bokulawula okungcono ubushushu be-silicone (ubushushu obuphantsi okanye i-silicone preheating).

Kule mihla, uluhlu lwezicelo zeemveliso zerabha ye-silicone luya luba banzi kwaye lubanzi, kwaye ukubumba inaliti ye-LSR kuyindima ebalulekileyo kweli shishini.

Isebenza njani i-Liquid Silicone Rubber Molding?
Ukubumba i-LSR kwahluka kancinane kwisitofu se-thermoplastic ngenxa yokuguquguquka kwayo. Njengesixhobo esiqhelekileyo se-aluminium, isixhobo sokubumba i-LSR senziwe kusetyenziswa i-CNC machining ukwenza isixhobo sobushushu obuphezulu esakhiwe ukumelana nenkqubo yokubumba i-LSR. Emva kokugaya, isixhobo sigudiswa ngesandla kwiinkcukacha zomthengi, ezivumela iinketho ezintandathu zokugqiba umgangatho.

Ukusuka apho, isixhobo esigqityiweyo silayishwa kwi-LSR-specific injection molding press echanekileyo elungiselelwe ukulawula ngokuchanekileyo ubungakanani bokudubula ukuvelisa iindawo ze-LSR ezihambelanayo. Kwi-Mold-Making, iinxalenye ze-LSR zisuswa ngesandla kwi-mold, njengoko izikhonkwane ze-injector zinokuchaphazela umgangatho wenxalenye. Izinto ze-LSR zibandakanya ii-silicone eziqhelekileyo kunye namabakala athile ukuze alingane kwizicelo ezahlukeneyo kunye namashishini afana nezonyango, iimoto kunye nokukhanya. Ekubeni i-LSR i-polymer ye-thermosetting, isimo sayo esibunjiweyo sisisigxina-xa sele simisiwe, ayikwazi ukunyibilika kwakhona njenge-thermoplastic. Xa ukubaleka kugqityiwe, iinxalenye (okanye isampuli yokuqala yokuqhuba) zifakwa ebhokisini kwaye zithunyelwa ngokukhawuleza emva koko.

Apha masiyiphonononge, okokuqala, kufuneka sithethe malunga nemathiriyeli yerabha ye-silicone, iingongoma eziphambili omele uzazi ngolu hlobo lulandelayo:
Irabha yesilicone elulwelo (LSR) yeyona igqwesileyo yokugquma, ilungele umgangatho ophezulu okanye iplagi ye-elektroniki yobuchwepheshe obuphezulu.
Izinto zerubha ye-silicone yolwelo (LSR) zilungele ukusetyenziswa kwindawo yobushushu obuphezulu okanye kwindawo yobushushu obuphantsi. Iimpawu zokugquma, iipropathi zoomatshini, kunye neempawu ezibonakalayo zezixhobo zihlala zingatshintshi kwi-200 ℃ okanye ephantsi njenge -40 ℃.
Inganyangeki kwi-gasification kunye nokuguga, ngoko ifanelekile kwizicelo zangaphandle.
Irabha ye-silicone yolwelo (LSR) ayinyangeki ngeoyile, ingasetyenziswa kwishishini lemigodi yeoli. Kukho iimodeli ezimbini: umatshini wokubumba we-abicah owenziwe ngokuthe nkqo we-slide, umatshini wokubumba we-silicone othe nkqo wesilayidi, osetyenziselwa ukuvelisa zonke iintlobo zeemveliso zerabha ezichanekileyo ezichanekileyo; umatshini wokutofa nge-cylinder angle esezantsi, kukuveliswa kwee-insulators zokuxhoma ezihlanganisiweyo, i-Post insulators kunye neemodeli zemveli zokubamba.

Ukubunjwa kwesitofu se-LSR
Itekhnoloji entsha ihlangabezana neemfuno zabathengi:
Irabha ye-Silicone ye-Liquid (LSR) inokucutshungulwa kwi-liquid injection molding (LIM) inkqubo. I-liquid ekrwada ixutywe kumacandelo amabini ahlukeneyo kumlinganiselo we-1: 1 kwaye itofwe nge-cold-runner-system ibe ngundo oshushu. Unyango lwenzeka kwimizuzwana, kunika inzuzo yokukhwela ibhayisekile ngokukhawuleza kunye nokuveliswa kwezinto ezininzi.

Ngenxa yokuguquguquka kuyilo kunye nokusetyenziswa kwezixhobo, ukubumba inaliti ye-LSR ilungile ekuveliseni iijiyometri ezintsonkothileyo kwaye inokudibanisa imisebenzi eyahlukeneyo ibe yinxalenye enye. Ikwabonelela ngeenzuzo ezibalulekileyo malunga nokuthembeka kwemveliso kunye neendleko ezipheleleyo zobunini.

Iyunithi yokutofa ye-silicone yolwelo ibaleka ipholile ngomphanda wamanzi opholileyo kunye nombhobho ukuthintela i-silicone engamanzi ukuba inganyangeki. Iiyunithi zokutofa kwe-Thermoplastic ziqhuba ngendlela echaseneyo, zidinga umgqomo kunye nomlomo wokufudumala ukuya kwi-300F okanye ngaphezulu ukugcina izinto ezihambayo. Iiyunithi zokubumba inaliti yolwelo nazo ziqhuba kuxinzelelo olusezantsi (phantsi kwe-1,000 PSI), ngelixa abalingane babo be-thermoplastic babaleka kumashumi amawaka e-PSI.

I-silicone yolwelo idla ngokubonelelwa nge-5 gallon pail okanye i-55 gallon drums. Kukho inxalenye ye-A kunye neCandelo B. I-Colourants iza ngendlela ye-dispersions kwaye ngokuqhelekileyo i-1-3% ngobunzima be-silicone edibeneyo. I-silicone ye-dousing unit ipompo inxalenye ye-silicone kunye ne-silicone inxalenye ye-B ngokusebenzisa i-hoses eyahlukileyo ukuya kumxube omileyo. Ukongeza, umbala umpontshelwa kumxubi omileyo kusetyenziswa elinye ithumbu. Amacandelo axubileyo afakwe emqaleni wesitofu sokubumba umbhobho ngendlela yevalve yokuvala.

I-DJmolding yirabha elulwelo lwe-silicone yolwelo (LSR) yokubumba inaliti kunye nomenzi wamalungu erabha elulwelo oluvela eTshayina.

Kweli nqaku, siza kuxoxa ngeenzuzo zokubumba inaliti ye-LSR kwaye siphonononge usetyenziso olwahlukeneyo lobu buchwepheshe.

Isebenza Njani I-LSR I-Injection Molding?

I-LSR (i-Liquid Silicone Rubber) yokubumba inaliti yinkqubo yokuvelisa evelisa umgangatho ophezulu, iindawo ezichanekileyo zerabha ye-silicone. Kuluncedo ekudaleni iimilo ezintsonkothileyo kunye noyilo oluneenkcukacha ezigqwesileyo kunye nokungaguquguquki. Inkqubo ibandakanya ukutofa irabha ye-silicone elulwelo kwindawo yokungunda, ukuyivumela ukuba inyange kwaye iqine kwimilo efunekayo. Nantsi inkcazo emfutshane malunga nendlela isitofu se-LSR esisebenza ngayo:

Ukulungiselela ukungunda: Inkqubo iqala ngokulungiselela ukungunda. Umngundo udla ngokuba neziqingatha ezibini, icala lenaliti, kunye necala elibambekayo, elidibanayo ukwenza umngxuma wesilicone. Emva kokunyanga, isikhunta siyacocwa kwaye sigqutywe nge-arhente yokukhulula ukuququzelela ukususwa kwenxalenye elula.

Ukulungiswa kwe-Silicone: I-rubber ye-silicone ye-Liquid yinto enezinto ezimbini eziqulethwe kwisiseko se-silicone kunye ne-agent ephilisayo. La macandelo axutywe kunye ngomlinganiselo ochanekileyo. Umxube uhlanjululwe ukuze ususe nawaphina amaqamza omoya angachaphazela umgangatho wenxalenye yokugqibela.

Isitofu: Irabha ye-silicone exutywe kunye ne-degassed liquid idluliselwa kwiyunithi yokutofa. Iyunithi yokutofa itshisa izinto kwiqondo lokushisa elithile ukunciphisa i-viscosity yayo kwaye yenza kube lula ukuhamba. Izinto eziphathekayo zifakwe kwi-mold cavity nge-nozzle okanye i-sprue.

Ukunyanga: Nje ukuba irabha ye-silicone yolwelo itofwe kumgodi wokungunda, iqala ukuphilisa. Inkqubo yokunyanga idla ngokuqalwa bubushushu, nangona ezinye iimbumba zinokusebenzisa ezinye iindlela, ezinje ngokukhanya kwe-UV. Ubushushu bubangela ukuba i-silicone inqumle kwaye iqiniswe, yenze i-mold cavity. Ixesha lokunyanga liyahluka ngokuxhomekeke kuyilo lwenxalenye kunye nempahla ye-silicone.

Ukupholisa kunye nokususwa kwenxalenye: Emva kwenkqubo yokunyanga, isikhunta sipholile ukuvumela ukuba i-silicone ibekwe ngokupheleleyo. Ixesha lokupholisa linokwahluka kodwa lifutshane kunexesha lokunyanga. Xa sele ipholile, isikhunta siyavulwa, kwaye inxalenye egqityiweyo iyasuswa. Isikhundla sinokufuna amanyathelo ongezelelweyo emva kokulungiswa, njengokucheba izinto ezingaphezulu okanye ukuhlola naziphi na iziphene.

Ukubumba inaliti ye-LSR kunika iingenelo ezininzi, kubandakanya ukuvelisa iijiyometri ezintsonkothileyo nezintsonkothileyo, ukuhambelana okugqwesileyo kwenxalenye, ukuchaneka okuphezulu, kunye nokumelana nobushushu obugqithisileyo, iikhemikhali, kunye nokwaluphala. Isetyenziswa ngokuqhelekileyo kumashishini ahlukeneyo ezonyango, ezemoto, eze-elektroniki, kunye neemveliso zabathengi.

Kubalulekile ukuqaphela ukuba le yingcaciso eyenziwe lula yenkqubo yokubumba inaliti ye-LSR, kwaye umsebenzi wokwenene unokwahluka ngokuxhomekeke kwisixhobo esithile, iimathiriyeli, kunye nenxalenye yeemfuno.
