I-Silicone yePakethe yePlastiki yeCosmetic
Irabha yesilicone, njengezinto ezibonakalayo, isetyenziswa kakhulu kwiibhotile zokuhamba, iibhotile zokwahlulahlula, izipho, kunye nezixhobo zokuphulula. Njengezinto ezinobuhlobo nokusingqongileyo, okwangoku isetyenziswa kakhulu kwiimveliso zabasetyhini nabantwana, izinto zokuthambisa, izinto zokuthambisa, iimveliso zonyango, izinto zangaphandle nezokuzonwabisa, kunye nefenitshala. Ngokusetyenziswa rhoqo kweefomyula ezisekelwe kwizityalo kushishino lwezithambiso, kulindeleke ukuba ukusetyenziswa kwerabha yesilicone kweli shishini kubonise ukukhula okukhulu kwixesha elizayo.
I-Silicone, sisixhobo sokufunxa esisebenza kakhulu kwaye siyinto engeyiyo i-crystalline enefomyula yekhemikhali i-mSiO2·nH2O. Ayinyibiliki emanzini nakweyiphi na into enyibilikisayo, ayinavumba, ayinancasa, kwaye izinzile ngokweekhemikhali. Ayisebenzi nayo nayiphi na into ngaphandle kwe-alkali enamandla kunye ne-hydrofluoric acid. Iintlobo ezahlukeneyo ze-silicone zinezakhiwo ezahlukeneyo ze-micro-pore ngenxa yeendlela ezahlukeneyo zokwenza. Ulwakhiwo lweekhemikhali kunye nolwakhiwo lomzimba lwe-silicone lumisela iimpawu ezininzi ezinzima ukuthathelwa indawo zezinye izinto ezifanayo: ukusebenza okuphezulu kokufunxa, ukuzinza okuhle kobushushu, iipropati zekhemikhali ezizinzileyo, kunye namandla aphezulu oomatshini.
Iimveliso zesilicone ezibunjiweyo zihlala zenziwa ngokubeka izinto eziluhlaza zerabha yesilicone eqinileyo kunye nee-agents ezongeziweyo ze-vulcanizing kwi-molds ezinobushushu obuphezulu kwaye zifake uxinzelelo ngomatshini we-vulcanizing kubushushu obuphezulu. Ubunzima be-silicone ebunjiweyo buhlala buphakathi kwama-30°C nama-70°C. Izinto eziluhlaza zixutywa neepaste zemibala ukuze zihambelane nemibala ngokwetshathi yombala wePantone. Imilo ye-mold imisela imilo yemveliso yesilicone ebunjiweyo. Iimveliso zesilicone ezibunjiweyo okwangoku zezona zisetyenziswa kakhulu kushishino lwesilicone.
Iimveliso ze-silicone ezikhutshiweyo zihlala zenziwe ngokukhutshelwa kwe-silicone ngomatshini wokukhupha. Ngokubanzi, i-silicone ekhutshiweyo ikwimo yeemicu ezinde okanye iityhubhu ezinokunqunyulwa kuyo nayiphi na ubude. Nangona kunjalo, imilo ye-silicone ekhutshiweyo ilinganiselwe. Isetyenziswa kakhulu kwizixhobo zonyango nakwimishini yokutya.
Iimveliso ze-silicone ezingamanzi zenziwa ngokufaka i-injection molding okanye ngokufaka i-spray molding. Ezi mveliso zithambile, zinobunzima obuqala kwi-10°C ukuya kwi-40°C. Ngenxa yokuthamba kwazo, zisetyenziswa kakhulu ekulinganiseni amalungu omzimba womntu, ii-breast pads ze-silicone zonyango, kunye nezinye izinto ezisetyenziswayo.
