☑ Kubika no gutanga
Igomba kubikwa no gutangwa mugihe cyumye kandi gisukuye muburyo bwa paki yambere kandi kure yubushyuhe.Ipaki imaze gufungurwa kugirango ikorwe, hagomba gufatwa ingamba zifatika kugirango hirindwe amazi.
Gupakira: 25kg / igikapu, impapuro nyinshi zipakurura plastiki igizwe numufuka hamwe na kare yo hepfo ya valve ifunguye, hamwe numufuka wimbere wa polyethylene.
☑ Ubuzima bwa Shelf
Igihe cya garanti ni imyaka ibiri.Koresha hakiri kare hashoboka munsi yubushyuhe bwinshi nubushuhe, kugirango utongera amahirwe yo guteka.
☑ Umutekano wibicuruzwa
Hydroxypropyl methyl selulose HPMC LK20M ntabwo ari mubintu byangiza.Andi makuru yerekeye umutekano atangwa murupapuro rwumutekano wibikoresho.
Ibibazo
Hydroxypropyl methylcellulose (HPMC) ni ethers ya selile ifite amatsinda ya hydroxyl kumurongo wa selile yasimbujwe methoxy cyangwa hydroxypropyl.It ikorwa na etherification idasanzwe ya pamba selile nziza cyane mubihe bya alkaline.Mu myaka yashize, HPMC, nkimikorere ikora, ahanini igira uruharesmu gufata amazi no kubyimba mubikorwa byubwubatsi kandi bikoreshwa cyaneminisiteri yumye, nka tile yometseho, grout, guhomesha, gushira urukuta, kuringaniza, minisiteri yububiko nibindi.
Mubisanzwe, kubifu ya putty, viscosity yaHPMCbirahagije hafi 70.000 kugeza 80.000.Ibyibanze byibanze kumikorere yo gufata amazi, mugihe ingaruka zo kubyimba ari nto.Kuri minisiteri, ibisabwa kuriHPMCziri hejuru, kandi ibishishwa bigomba kuba hafi 150.000, bishobora kwemeza ko ikora neza mumabuye ya sima.Byumvikane ko, ifu yuzuye, mugihe cyose ibikorwa byo gufata amazi ya HPMC ari byiza, nubwo ibishishwa biri hasi (70.000 kugeza 80.000), biremewe.Nyamara, muri sima ya sima, nibyiza cyane guhitamo HPMC ifite ubwiza bunini (burenga 100.000), kubera ko ingaruka zayo zo gufata amazi ari ingenzi muri ibi bihe.
Ikibazo cyo gukuramo ifu ya putty ahanini biterwa nubwiza bwa calcium hydroxide kandi ntaho ihuriye na HPMC.Niba calcium ya hydroxide ya calcium iri hasi cyangwa igipimo cya CaO na Ca (OH) 2 kidakwiye, birashobora gutuma ifu ya putty igwa.Kubyerekeye ingaruka za HPMC, bigaragarira cyane cyane mubikorwa byo gufata amazi.Niba imikorere yo gufata amazi ya HPMC idahwitse, irashobora kandi kugira ingaruka runaka kubutaka bwifu yifu.
Ibisabwa kugirango ukoreshe ifu ya putty ni bike.Ubukonje bwa 100.000 burahagije.Urufunguzo ni ukugira ibintu byiza byo gufata amazi.Kubijyanye na minisiteri, ibisabwa birasa naho biri hejuru kandi birakenewe cyane, kandi ibicuruzwa 150.000 bifite ingaruka nziza.
