Irabha luhlobo lwerabha ethambileyo esiyaziyo sonke, kwiindawo ezininzi zemizi mveliso sinokuyibona, kunye ne-silicone kunye nerabha ukuze abahlobo abaninzi bangakwazi ukuchonga iiyantlukwano zabo, abantu abaqhelekileyo bahlala bephosa i-silicone yezinto zerabha, kunye ne-silicone yokwenyani iya kuba yimpazamo. kwizinto eziphathekayo ze-latex, ngoko ke ungakhankanyi ibakala le-silicone kunye nomahluko, Ke abantu abayaziyo irabha kunye nezixhobo zeplastiki bayazi ukuba kukho amanqanaba amaninzi ahlukeneyo kunye nokwahlukana phakathi kwe-silicone kunye ne-rubber, njenge-rubber yendalo, i-butyl, i-chloroprene, i-rubber fluorine, kunye ne-silicone nayo inamanqanaba, afana nebakala lemizi-mveliso, ibakala lokutya, ibakala lezonyango, uya kwahlula umahluko wabo!

I-silicone kuyo yonke i-colloid ethambileyo yenye yezona zinto zisebenza kakuhle, kuyo yonke imiba yeempawu ikumgangatho obanzi ngakumbi, amashishini amaninzi akhethe ukuyisebenzisa njengomzimba ophambili okanye iindawo ezisecaleni, kunye nebakala lokutya kunye nebakala eliqhelekileyo nalo. yahlulwe kwisigaba segesi kunye nenqanaba lemvula, umahluko phakathi kwezi zimbini kukuba iipropathi ezihlanganisiweyo zezinto zahlukile, umzimba oyintloko uyafana.

Ngokomzekelo, i-silicone ye-precipitated ikakhulu i-silica emnyama.Le silica emnyama isebenzisa i-oyile kunye negesi kubushushu obuphezulu ukulungiselela i-sodium silicate eyenziwe nge-carylonisha kunye nothuthu lwesoda kwisisombululo esixubileyo soxinaniso oluphezulu, kwaye yongeza iikhompawundi ezithile ngokucoca, ukuhluza kunye nokutyumza ukufumana i-silica emnyama emnyama.Yongeza ioli ye-silicone, i-silica kunye nezinye izinto ukuze ufumane imathiriyeli ekrwada yerabha ye-silicone.

I-silicone yomphunga oku kukusetyenziswa kwe-silicon tetrachloride ukutsha kwesilicon dioxide ukongeza ioli ye-silicone, i-silica emnyama, i-siloxane kunye nezinye izinto ukufumana imathiriyeli ye-silicone yomphunga, eyaziwa ngokuba yi-silicone yebakala lokutya, ubuninzi bayo obuphezulu, iinkcukacha ze-silicon zemolekyuli ziyakwazi. ibe ngaphezulu kwe-1000 ye-mesh, ke imveliso iphinda iphinde ibuyele, ukuxhathisa ukukrazula kungcono kunemathiriyeli ye-silicone eqhelekileyo, kodwa ixabiso libiza kakhulu.

Kodwa oqhelekileyo mna nawe asinakukwazi ukuxelela ngeso lenyama ukuba imveliso ye-silicone yeyezinto eziqhelekileyo ze-silicone okanye i-abicah yebanga lokutya, ngoko ekuphela kwendlela kukusebenzisa ubuchule bokuchonga, umzekelo, xa ukuveliswa kwe-tensile rebound, i-silicone eqhelekileyo iya kubonakala inkungu emhlophe ibonakala kumphezulu wokolula icace ngakumbi, ngelixa iglu yesigaba segesi ayiyi kuvelisa into emhlophe yenkungu xa isolula.

Okwesibini, ekutshani kukutsha kwezinto eziqhelekileyo ze-silicone kuya kubonakala umsi omhlophe, kodwa amasuntswana omgubo emva kokutshiswa kwemveliso ayinto enkulu kwaye kulula ukuyidilika, kwaye iglu yesigaba segesi iya kubonakala le nto, kodwa Umgubo wokutsha we-silicone yebakala lokutya uya kuba mhle, kwaye akukho lula ukudilika, ixesha lokutsha lide kuneglu eliqhelekileyo lemvula.

Ke xa uzichonga, unokwazi ngokusisiseko ukuba ngaba zingamabakala okutya okanye izixhobo eziqhelekileyo zebakala ngesandla.Kodwa ke, akunjalo ukuba iglue eqhelekileyo ayikwazi ukuhlangabezana neemfuno zokhuseleko kunye nokukhuselwa kwendalo.Okwangoku, izinto ze-silicone zebakala lokutya zisetyenziswa kakhulu ebomini apho kukho ukunxibelelana ngakumbi nomzimba kunye nolusu, njengempahla yasekhitshini ye-silicone, iimfuno zemihla ngemihla ze-silicone, i-silicone pacifiers, kunye neglu eqhelekileyo isetyenziswa kwizixhobo zombane.Izitywina zeSilicone, i-silicone gaskets njalo njalo, ngoko kukho ukungafani.
