HEC ili ndi ntchito yokulitsa ndikuwongolera mphamvu zomangira za zokutira mu utoto wa latex.
HEC (Hydroxyethyl cellulose) ndi polima wosungunuka m'madzi wokhala ndi kusintha kwa viscosity, kusungunuka m'madzi ndi zosungunulira za organic, ndipo zimatha kupanga emulsion yokhazikika m'madzi.Ili ndi kukana kwambiri kwa halogen, kukana kutentha ndi alkali, komanso kukhazikika kwamankhwala.HEC ntchito kusintha mamasukidwe akayendedwe a latex utoto, kukhazikika katundu chilinganizo, kupewa agglomeration wa utoto utoto, kusintha adhesion, kumakoka mphamvu, kusinthasintha ndi kuvala kukana ❖ kuyanika ❖ kuyanika filimu, amene ndi chigawo cha luso la chitukuko cha. utoto wapamwamba kwambiri wa latex.
Ntchito yayikulu ya HEC ndikuwongolera zida zamakina za zokutira.Itha kugwiritsidwanso ntchito ngati anti-sedimentation agent, preservative kapena anti-viscosity agent.Popanda ndende ya HEC, imatha kuonjezera kutsekemera kwa zokutira, kuonjezera mphamvu zowonongeka ndi kusinthasintha kwa zokutira, ndikuchotsa kuphulika ndi ming'alu ya filimuyo.
Ma cellulose a Hydroxyethyl amapereka zokutira zabwino kwambiri zokutira za latex, makamaka zokutira za PVA zapamwamba.Pamene zokutira ndi wandiweyani, flocculation sichitika.
Ma cellulose a Hydroxyethyl ali ndi mphamvu yakukhuthala kwambiri.Ikhoza kuchepetsa mlingo, kupititsa patsogolo chuma cha ndondomekoyi, komanso kupititsa patsogolo kukana kwa kupaka kwa zokutira.
Njira yamadzimadzi ya hydroxyethyl cellulose si ya Newtonian, ndipo katundu wa yankho amatchedwa thixotropy.
M'malo osasunthika, makina opaka amakhalabe okhuthala komanso otseguka pambuyo poti mankhwalawa asungunuka kwathunthu.
M'malo otsanuliridwa, dongosololi limakhala ndi kukhuthala pang'ono, zomwe zimapangitsa kuti mankhwalawa azikhala ndi madzi abwino kwambiri, ndipo samawombera.
Mu burashi ndi mpukutu wokutira, mankhwalawa ndi osavuta kufalikira pa gawo lapansi.Yabwino yomanga.Pa nthawi yomweyi, imakhala ndi kukana kwabwino kwa splash.Chophimbacho chikatsirizika, kukhuthala kwa dongosolo kumabwezeretsedwa nthawi yomweyo, ndipo chophimbacho nthawi yomweyo chimatulutsa kutuluka kolendewera.
