ISilicone Potting Compound VS Epoxy Potting Compound-Yeyiphi Engcono?

Ukubumba kukugcwalisa okanye ukubethelela iindibano ze-elektroniki okanye izinto ezinentlaka kwindawo ebiyelweyo ukuzigcina zikhuselekile kwiingozi. Ukuzinzisa kungenziwa ngokuyinxenye okanye ngokupheleleyo, kuxhomekeke kumanqanaba okhuseleko afunekayo kwisicelo esinikiweyo. Iikhompawundi zokubumba nceda ukuphucula ukugquma kombane, ukuchithwa kobushushu, kunye neempawu zokunqanda umlilo. Iikhompawundi ezisetyenziswa kwi-electronics, kwiimeko ezininzi, izikhuselo ezisisigxina ezinyamezela zonke iimeko ezikhusela indibano.

I-Electronics iqulethe izinto ezinobuthathaka kunye nezibalulekileyo ezinokonakala ngokulula xa zibekwe kwindawo enzima kunye nezoyikiso. Umhlwa, ukungcangcazela, iimeko zemozulu, uthuli, ubushushu, kunye nohlaselo lwekhemikhali zezinye izoyikiso ezenziwa ngamacandelo kwaye zifuna ukukhuselwa kuzo. Ezona zinto zisetyenziswa ngokuqhelekileyo ukwenza imbiza yi-epoxy, silicone, kunye ne-polyurethane.

Iikhompawundi ze-epoxy kunye ne-silicone zonwabela ukuthandwa ngokulinganayo ngenxa yeempawu zazo eziphezulu kwiikhompawundi ze-polyurethane. I-Epoxy yinto ehlala ixesha elide yokubumba esetyenziswa rhoqo kwiibhodi zesekethe eziprintiweyo ngenxa yokumelana kwayo neekhemikhali eziphezulu. Esi sixhobo sikwabonelela ngeempawu eziphezulu zokubambelela, phakathi kwezinye izinto, ezenza kube lukhetho olukhulu kwizicelo ezahlukeneyo. Ukunyangwa kwe-resin, nangona kunjalo, kuthatha ixesha.

I-Silicone yomelele kwaye iguquguquka njengekhompawundi yokubumba, iyenza ibe luncedo kakhulu kwizicelo ezivezwe kumaqondo obushushu agqithisileyo. Kodwa xa kuthelekiswa ne-epoxy, i-silicone iyabiza, iyenza ukuba ingalungeli usetyenziso olulula. Ngokujonga i-silicone ikhompawundi yeembiza vs. epoxy, kufuneka ukwazi ukugqiba ukuba yeyiphi imathiriyeli eyenza ukhetho olungcono kwiimfuno zakho zokubumba.

Iipropati ezinganyangekanga 

Ukuthelekisa izinto ezimbini zokubumba, kungcono ukujonga iipropati kwiindawo eziphilileyo nezinganyangekiyo.

Iindleko zezinto -Xa uthenga izinto zokubumba, i-silicone ixabisa ngaphezu kwe-epoxy, enexabiso eliphakathi. I-Epoxy ifikeleleka ngakumbi kwaye ngenxa yoko ikhethwa ngabasebenzisi abaninzi.

Ukulula ukuphatha -Xa kuziwa ekuphatheni, i-silicone ilula kakhulu ukusebenzisana nayo, ngelixa i-epoxy ayinzima kodwa idinga ulwazi oluthile lokufezekisa iziphumo ezifunwayo.

Isantya sokunyanga -Ababini iikhompawundi potting Tshatisa amandla okuphilisa njengoko omabini anganyanga ngokukhawuleza okanye kancinci ngokuxhomekeke kwiimfuno zesicelo. Bangayekwa ukuba banyange kwiqondo lobushushu begumbi okanye inkqubo ikhawuleziswe ngokufakwa kobushushu.

Uvakalelo lokufuma -Kwifomu enganyangekiyo, i-epoxy inokuchaphazeleka kumswakama, ngelixa i-silicone inovakalelo oluphantsi kakhulu. Ngoko ke, ayifaki emngciphekweni wokonakala ngenxa yokufuma.

Iipropati eziNyango 

ukuqina -Kwifomu enyangisiweyo, i-epoxy iqinile kwaye iqinile, ngelixa i-silicone ithambile kwaye ibhetyebhetye. Ngoko ke zifaneleke kwizicelo ezahlukeneyo, kunye ne-silicone eyenza ukhetho olungcono kumacandelo anokuthi wonakaliswe bubungqongqo beekhompawundi ze-epoxy.

zokudibanisa -Xa kuziwa ekunamatheleni, i-epoxy igqwesile, kwaye i-silicone ilungile. I-epoxy adhesion inokuhlala ubomi bonke, kodwa ukufezekisa umgangatho ophezulu ofanayo njenge-silicone, kufuneka uyixube kunye nezinye iikhemikhali ezilukhuni.

Ukumelana nechemical - I-Epoxy ithatha isithsaba ngokubhekiselele kwiikhemikhali ezichasayo. I-Silicone inokumelana neekhemikhali ezimbi kakhulu kwaye ayifanelekanga kumalungu avezwe kwiikhemikhali.

Uxinzelelo lwamacandelo Ngenxa yokuqina kwayo, i-epoxy inokucinezela ngokulula izinto zombane xa kuthelekiswa ne-silicone ehlala igqwesile ngenxa yobunzima bayo. Enyanisweni, unokulindela ukongezwa kobunzima kwicandelo lakho xa usebenzisa i-epoxy potting compounds.

Ngaba ujonge ezona zixhobo zikumgangatho ophezulu zokubumba iikhompawundi? I-DeepMaterial ngumenzi wakho wokuya. Inkampani inesisombululo sayo yonke imfuno yokubumba.
