Diyaarinta xalka methylcellulose waxay ku lug leedahay dhowr tillaabo iyo tixgelin, oo ay ku jiraan xulashada darajada ku habboon ee methylcellulose, go'aaminta diiradda la rabo, iyo hubinta kala diris habboon.Methylcellulose waa isku-dhafan badan oo si weyn looga isticmaalo warshado kala duwan, oo ay ku jiraan dawooyinka, cuntada, iyo waxyaalaha la isku qurxiyo, taasoo ay ugu wacan tahay dhumucdeeda, gelling, iyo guryaha xasilinta.
1. Doorashada Darajada Methylcellulose:
Methylcellulose waxaa lagu heli karaa darajooyin kala duwan, mid walbana wuxuu leeyahay muuqaalo kala duwan iyo sifooyinka gelation.Doorashada darajada waxay kuxirantahay codsiga loogu talagalay iyo sifooyinka la rabo ee alaabta ugu dambeysa.Darajooyinka leh viscosity sare ayaa caadi ahaan loo isticmaalaa codsiyada u baahan xalal dhumuc weyn ama jeel, halka darajooyinka viscosity hoose ay ku habboon yihiin qaabab badan oo dareere ah.
2. Go'aaminta Xoog-ururinta La rabo:
U fiirsashada xalka methylcellulose waxay ku xirnaan doontaa shuruudaha gaarka ah ee codsigaaga.Xoojinta sare waxay keeni doontaa xalal dhumuc weyn ama jel, halka xoogga hoose uu noqon doono dareere badan.Waa lama huraan in la go'aamiyo diiradda ugu fiican ee ku salaysan isticmaalka loogu talagalay, iyada oo la tixgelinayo arrimo ay ka mid yihiin viscosity, xasiloonida, iyo waafaqsanaanta maaddooyinka kale.
3. Qalabka iyo Agabka:
Kahor intaadan bilaabin habka diyaarinta, soo aruuri dhammaan qalabka lagama maarmaanka ah iyo agabka:
Methylcellulose budada ah
Biyo nadiif ah ama dareere kale oo habboon
Qalabka kicinta (tusaale, kicinta birlabeedka ama kiciya mashiinka)
dhululubo ama koob wax lagu cabbiro oo qalin jabiyay
Beakers ama weelasha lagu qaso
Heerkulbeegga (haddii loo baahdo)
mitirka pH ama fiilooyinka tusaha pH (haddii loo baahdo)
4. Habka diyaarinta:
Raac tillaabooyinkan si aad u diyaariso xalka methylcellulose:
Tallaabada 1: Miisaamidda budada Methylcellulose
Isticmaalka cabbirka dhijitaalka ah, cabbir qiyaasta ku habboon budada methylcellulose iyadoo loo eegayo xoogga la doonayo.Waa lagama maarmaan in si sax ah loo miisaamo budada si loo gaaro viscosity-ka la doonayo iyo joogteynta xalka ugu dambeeya.
Talaabada 2: Ku darida Solvent
Ku rid qaddarka la qiyaasay ee budada methylcellulose weel nadiif ah oo qalalan.Si tartiib ah ugu dar dareeraha (tusaale, biyo la miiray) budada adigoo si joogto ah u walaaqaya.Ku darida dareeraha waa in si tartiib tartiib ah loo sameeyaa si looga hortago isku-duubnaanta iyo in la hubiyo kala-baxa isku midka ah ee methylcellulose.
Talaabada 3: Isku qas iyo Kala diri
Sii wad walaaqda isku dhafka ilaa budada methylcellulose ay si buuxda u kala firdhiso oo ay bilaabato inay milaan.Iyada oo ku xidhan darajada iyo fiirsashada methylcellulose ee la isticmaalay, kala dirid dhamaystiran waxay qaadan kartaa wakhti.Heerkulka sare wuxuu soo dadajin karaa habka kala dirida, laakiin iska ilaali inaad dhaafto xadka heerkulka lagu taliyey, sababtoo ah waxay saameyn kartaa sifooyinka xalka.
Tallaabada 4: Hagaajinta pH (haddii loo baahdo)
Codsiyada qaarkood, waxaa laga yaabaa inay lagama maarmaan noqoto in la hagaajiyo pH ee xalka methylcellulose si loo gaaro sifooyinka la rabo ama loo hagaajiyo xasilloonida.Isticmaal pH mitir ama fiilooyinka tusaha pH si aad u cabbirto pH ee xalka una hagaajiso hadba sida loogu baahdo adiga oo ku dara qadar yar oo aashito ah ama saldhig.
Tallaabada 5: Oggolaanshaha fuuq-celinta
Ka dib marka budada methylcellulose ay si buuxda u milmo, u ogolow xalka inuu fuuqbaxo muddo ku filan.Wakhtiga fuuq-celinta way kala duwanaan kartaa iyadoo ku xidhan darajada iyo fiirsashada methylcellulose ee la isticmaalay.Inta lagu jiro wakhtigan, xalku waxa laga yaabaa in uu sii maro dhumuc ama jeexid dheeraad ah, markaa la soco viscositykiisa oo hagaaji sida loo baahdo.
Talaabada 6: Homogenization (haddii loo baahdo)
Haddii xalka methylcellulose uu muujiyo joogteynta aan sinnayn ama isku-darka walxaha, isku-dhafka dheeraadka ah ayaa loo baahan karaa.Tan waxaa lagu gaari karaa in la sii walaaqo ama la isticmaalo homogenizer si loo hubiyo kala firdhinta isku midka ah ee qaybaha methylcellulose.
Tallaabada 7: Kaydinta iyo Maaraynta
Marka la diyaariyo, ku kaydi xalka methylcellulose weel nadiif ah oo si adag u xiran si aad uga hortagto faddaraynta iyo uumiga.Weelasha sida saxda ah loo calaamadeeyay waa inay muujiyaan feejignaanta, taariikhda diyaarinta, iyo xaalad kasta oo kaydineed oo khuseeya (tusaale, heerkulka, iftiinka iftiinka).Si taxadar leh u xalli xalka si aad uga fogaato daadato una ilaaliso daacadnimadeeda.
5. Cilad-bixinta:
Haddii budada methylcellulose aysan si buuxda u milmin, isku day inaad kordhiso wakhtiga isku dhafka ama hagaajinta heerkulka.
Burburinta ama kala firdhisanaanta aan sinnayn waxa laga yaabaa inay ka dhalato ku darista dareeraha si degdeg ah ama isku darka aan ku filnayn.Hubi in si tartiib tartiib ah loogu daro dareeraha oo si fiican loo walaaqo si loo gaaro kala firdhiso isku mid ah.
La qabsi la'aanta maaddooyinka kale ama darafyada pH waxay saameyn kartaa waxqabadka xalka methylcellulose.Tixgeli inaad hagaajiso qaabaynta ama aad isticmaasho waxyaabo kale oo lagu daro si aad u gaadho sifooyinka la rabo.
6. Tixgelinta Badbaadada:
Si taxadar leh ula tacaal budada methylcellulose si aad uga fogaato neefsashada ama taabashada maqaarka iyo indhaha.Xiro qalabka ilaalinta shakhsi ahaaneed ee habboon (tusaale, galoofyada, muraayadaha) marka aad gacanta ku hayso budada.
Raac habraacyada badbaadada saxda ah iyo tilmaamaha markaad la shaqaynayso kiimikooyinka iyo qalabka shaybaadhka.
Tuur wixii xal methylcellulose ah oo aan la isticmaalin ama dhacay iyadoo loo eegayo qawaaniinta deegaanka iyo habraacyada qashin-qubka kiimikada.
diyaarinta xal methylcellulose ah waxay ku lug leedahay doorashada fasalka ku habboon, go'aaminta diiradda la doonayo, iyo raacitaanka hab-tallaabo-tallaabo ee kala diri iyo homogenization.Markaad raacdo tilmaamahan oo aad tixgeliso taxaddarrada badbaadada, waxaad diyaarin kartaa xalalka methylcellulose ee ku habboon shuruudahaaga gaarka ah.
