HPMC LK500 oo ah Hoobiye Is-habeeya
Sharaxaada Alaabta
Hydroxypropyl MethylCellulose EtherLK500 waa wax lagu daro hoobiyeyaal u baahandareere sare. Shaqadeeda ugu weyn waa in ay kordhisohaynta biyahaawoodda iyo awoodda hakinta ee hoobiye oo waxay leedahay saameyn yar oo dareere ah.

☑ Kaydinta iyo keenista
Waa in lagu kaydiyaa oo lagu keenaa xaalado qallalan oo nadiif ah qaabkeedii asalka ahaa oo ka fog kulaylka. Ka dib marka xirmada loo furo wax soo saarka, dib-u-xidhid adag waa in la qaadaa si looga fogaado soo gelinta qoyaanka.
Xidhmada: 25kg/bac, bac isku dhafan oo waraaqo ah oo lakabyo badan leh oo leh furin labajibbaaran ee waalka hoose, oo leh bacda filimka polyetylen lakabka gudaha.
☑ Nolosha shelf
Muddada dammaanadda waa laba sano. U isticmaal sida ugu dhakhsaha badan ee suurtogalka ah heerkulka sare iyo qoyaanka sare, si aanay u kordhin suurtogalnimada keega.
☑ Badbaadada alaabta
Hydroxypropyl methyl cellulose HPMC LK10M kama mid aha walxaha khatarta ah. Macluumaad dheeraad ah oo ku saabsan dhinacyada badbaadada ayaa lagu bixiyay xaashida xogta badbaadada agabka.
FAQS
Hydroxypropyl methylcellulose (HPMC) waa ethers cellulose kuwaas oo lahaa kooxaha hydroxyl ee silsiladda cellulose oo lagu beddelay methoxy ama kooxda hydroxypropyl.It waxaa lagu sameeyaa etherification gaar ah oo ah cellulose suuf aadka saafiga ah oo hoos yimaada xaaladaha alkaline. Sannadihii ugu dambeeyay, HPMC, sida isku-darka shaqaynaya, ayaa inta badan door ka ciyaarasee haynta biyaha iyo dhumucyada warshadaha dhismaha oo si weyn loogu isticmaalohoobiyeyaasha drymix, sida koolada tile, grouts, malaasta, suufka gidaarka, is barbardhig, hoobiye dahaarka iyo iwm.
Caadi ahaan, budada putty, viscosity eeHPMCayaa ku filan qiyaastii 70,000 ilaa 80,000. Diirada ugu weyni waxay tahay waxqabadkeeda xajinta biyaha, halka saamaynta dhumucdu ay tahay mid yar. Hoobiyaha, shuruudaha loogu talagalayHPMCway sarreeyaan, oo mawjaduhu waxay u baahan yihiin inay noqdaan ilaa 150,000, taas oo hubin karta inay si fiican ugu shaqeyso hoobiye sibidhka. Dabcan, budada putty, ilaa inta waxqabadka haynta biyaha ee HPMC uu wanaagsan yahay, xitaa haddii viscosity uu hooseeyo (70,000 ilaa 80,000), waa la aqbali karaa. Si kastaba ha ahaatee, hoobiye sibidhka, waxa aad u fiican in la doorto HPMC oo leh maqaar weyn (in ka badan 100,000), sababtoo ah saameynteeda xajinta biyaha ayaa aad muhiim ugu ah xaaladdan.
Dhibaatada ka saarista budada putty inta badan waxay kuxirantahay tayada kaalshiyamka hydroxide oo wax yar kuma laha HPMC. Haddii maadada kaalshiyamka ee kalsiyum hydroxide ay hooseyso ama saamiga CaO iyo Ca (OH) 2 ay tahay mid aan habooneyn, waxay keeni kartaa in budada suufka ah ay hoos u dhacdo. Marka la eego saamaynta HPMC, waxay inta badan ka muuqataa waxqabadkeeda haynta biyaha. Haddii waxqabadka haynta biyaha ee HPMC ay liidato, waxa kale oo laga yaabaa inay saamayn gaar ah ku yeelato soo-buxinta budada putty.
Shuruudaha loo baahan yahay isticmaalka budada putty waa kuwo aad u hooseeya. 100,000 viscosity ayaa ku filan. Furaha ayaa ah in la helo sifooyin wanaagsan oo lagu hayo biyaha. Marka la eego hoobiye, shuruuduhu aad bay u sarreeyaan oo viscosity sare ayaa loo baahan yahay, 150,000 oo badeecada waxay leedahay saameyn wanaagsan.
