Imbali yoPhuhliso lwe-Oli ye-Silicone ye-Textile

Isithambisi se-silicone se-Organic saqala ngo-1950.Kwaye uphuhliso lwayo ludlule kwizigaba ezine.

1.Isizukulwana sokuqala se-silicone softener

Ngo-1940, abantu baqala ukusebenzisa i-dimethyldichlorosilance ukumithailaphukwaye yafumana uhlobo oluthile lokuthintela amanzi.Kwi-1945, u-Elliott we-American General Electric Company (GE) wafaka iifayibha kwisisombululo se-alkaline samanzi kunye ne-sodium methyl silanol.Emva kokufudumeza, ifayibha yayinempembelelo entle yokungangeni manzi.

Kwiminyaka yokuqala ye-50s, i-American Dow Corning Company yafumanisa ukuba amalaphu aphathwe yi-polysiloxane nge-Si-H ayenesiphumo esihle sokungena kwamanzi kunye nokungena komoya okukhulu.Kodwa imvakalelo yesandla yayingalunganga kwaye ifilimu ye-silicone yayinzima, ibhityile kwaye kulula ukuwa.Emva koko isetyenziswe kunye ne-polydimethylsiloxane (PDMS).Apho akufumananga kuphela isiphumo esihle sokungangeni manzi kodwa kunye nemvakalelo ethambileyo yesandla.Emva koko, nangona iimveliso ze-silicone kwihlabathi lonke ziphuhliswe ngokukhawuleza kwaye zigubungela iindidi ezininzi, ngokusisiseko zazizezomxube womatshini we-dimethyl.ioli ye-silicone, ezaziwa ngokudibeneyo njengemveliso yeoli ye-silicone.Babesisizukulwana sokuqala se-textile silicone softener.

Isizukulwana sokuqala se-silicone softeners ngqo emulsified ioli ye-silicone nge-emulsification mechanical.Kodwa ngenxa yokuba ioli ye-silicone ngokwayo ayinalo iqela elisebenzayo, elingenako ukubopha kakuhle kwilaphu kwaye ayinakuhlambeka.Ngoko ayiyi kuphumeza umphumo ofanelekileyo xa isetyenziswe yodwa.

2.Isizukulwana sesibini se-silicone softener

Ukuze unqobe iintsilelo zesizukulwana sokuqala se-silicone softener, abaphandi baye bafumanisa isizukulwana sesibini se-silicone emulsion kunye ne-hydroxyl caps.I-softener ikakhulu yayibandakanya i-emulsion yeoli ye-hydroxyl ye-silicone kunye ne-hydrogen silicone emulsion yeoli, enokuthi yenze i-network crosslinking structure kumphezulu welaphu phambi kwe-catalyst yetsimbi, inika amalaphu ukuthamba okukhulu, ukuqina kunye nokuzinza.

Kodwa ngenxa yokuba inomsebenzi omnye kwaye i-oyile yachithwa ngokulula kwaye yadadayo, yatshintshwa sisizukulwana sesithathu se-silicone softener ngaphambi kokuba isetyenziswe ngokubanzi.

3.Isizukulwana sesithathu se-silicone softener

Isizukulwana sesithathu seisithambisi siliconeiphuhlise eyona ikhawulezayo phakathi kwayo evela kwiminyaka yakutshanje.Yazisa amanye amacandelo okanye amaqela asebenzayo kwimixokelelwane ephambili okanye yecala le-polysiloxane, njengeqela le-polyether, iqela le-epoxy, iqela le-alcohol hydroxyl, iqela le-amino, iqela le-carboxyl, iqela le-ester, iqela le-sulfhydryl, njl. yonke imiba yamalaphu.Kwakhona ukuthembela kumaqela, kunokunika amalaphu isitayela esahlukileyo.

Kodwa ngokubanzi isizukulwana sesithathu sesithambisi se-silicone kufuneka sidityaniswe ne-polysiloxane ye-monofunctional ukufezekisa isiphumo esifunekayo sonyango.Kunzima ukulawula izinga lokudibanisa, eliphembelele kakhulu imveliso kunye nokusetyenziswa.

4.Isizukulwana sesine se-silicone softener

Isizukulwana sesine sesithambisi se-silicone siphinde salungiswa isizukulwana sesithathu se-silicone softener ngokwesiphumo esifunekayo sokugqiba ilaphu.Oko kwazisa amaqela asebenzayo ngakumbi, anokwanelisa zonke iimfuno zokusetyenzwa kwelaphu ngaphandle kokudibanisa.

Amalaphu aphathwa ngesithambisi sesilicone esilungisiweyo esineentlobo ezahlukeneyo zamaqela asebenzayo anophuculo olukhulu ekuthambeni, ukuvaleka, ukunwebeka kunye ne-hydrophilicity, njl. njl ekhoyo.
