Waa maxay Skim jaakad?

Jaakad jilicsan waa lakab khafiif ah oo shay ah oo lagu dhejiyay gidaarka ama saqafka si loo khafiifiyo cilladaha oo loo abuuro meel siman oo rinjiyeynta ama gidaarada. Walaxda loo isticmaalo daahan barafka ah ayaa caadi ahaan isugu jira biyo, sibidh, iyo waxyaabo kale oo lagu daro sida ether cellulose.

Eter cellulose waa polymer-biyood-milmi leh oo ka soo jeeda cellulose dabiiciga ah. Waxaa si weyn loogu isticmaalaa warshadaha dhismaha sidii dhumuc, xasiliye, binder, iyo wakiilka biyaha haynta. Marka laga hadlayo jaakad jilicsan, ether cellulose ayaa lagu daraa isku dhafka si loo helo karti-shaqsiyeed oo hagaagsan iyo guryaha ilaalinta biyaha.

Mid ka mid ah doorarka muhiimka ah ee ether-ka cellulose ee jaakad jilicsan ayaa ah awoodda ay u leedahay inay dhumucdo isku dhafka. Jaakad dhuuban waxay u baahan tahay in ay ahaato mid dhuuban oo si fudud ugu faafsan dusha sare laakiin dhumuc ku filan si ay u buuxiso wixii banaan ama cillado ah. Eter cellulose waxay ka caawisaa in la gaaro joogteynta saxda ah iyadoo la adkeynayo isku dar ah, taasoo sahlaysa in si siman loogu faafo dusha sare.

Shaqada kale ee muhiimka ah ee ether-ka cellulose ee jaakad jilicsan waa awoodda ay u leedahay in ay biyaha ceshato. Jaakad jilicsan waxay u baahan tahay inay qoyaan muddo cayiman si loo hubiyo ku dheggan habboon iyo si looga hortago dildilaaca ama yaraanta. Eter-ka Cellulose wuxuu caawiyaa in biyaha lagu hayo isku darka, taas oo hoos u dhigta habka qalajinta oo hubisa in jaakad jilicsan ay si habboon u dejiso.

Eter cellulose sidoo kale wuxuu u shaqeeyaa sidii xire ee jaakad jilicsan, ka caawinta in la isku daro isku dar ah oo hagaajinaysa ku dheggan dusha sare. Tani waxay hubineysaa in jaakad jilicsan ay sameyso xiriir adag oo dusha sare ah, abuurista siman iyo xitaa dusha sare ee rinjiyeynta ama waraaqaha gidaarka.

Tayada iyo waxqabadka jaakad jilicsan ayaa si weyn u saameeya nooca iyo qiyaasta etherka cellulose ee la isticmaalo. Waxaa jira noocyo kala duwan oo ether-ka cellulose ah oo laga heli karo suuqa, sida hydroxyethyl cellulose (HEC), methyl cellulose (MC), iyo carboxymethyl cellulose (CMC). Nooc kastaa wuxuu leeyahay sifooyin iyo astaamo kala duwan, doorashada nooca saxda ah iyo qaddarka saxda ah ayaa muhiim u ah go'aaminta tayada jaakad jilicsan.

Marka la soo koobo, ether cellulose ayaa door muhiim ah ka ciyaara soo saarista jaakad jilicsan. Waxay siisaa dhumucda lagama maarmaanka ah, isku-xidhka, iyo guryaha haynta biyaha ee isku dhafka ah, taas oo hubinaysa awooddeeda, wanaajiso adhesion, oo ka hortagta dildilaaca ama yaraanta. Doorashada nooca saxda ah iyo qadarka ether cellulose waa lagama maarmaan in la soo saaro jaakad jilicsan oo tayo sare leh oo buuxisa heerarka la rabo ee warshadaha dhismaha.
