VAE powders RDP (Redispersible) polymer powders ke li-additives tse sebelisoang hangata indastering ea kaho.E eketsoa ho lihlahisoa tse thehiloeng ho samente tse kang li-adhesives tsa lithaele, metsoako ea ho itšehla thajana le mekhoa ea ho thibela marako a ka ntle ho ntlafatsa thepa e kang ho sebetsa, ho khomarela le ho feto-fetoha ha maemo.Boholo ba likaroloana, bongata ba bongata le viscosity ea phofo ea polymer ea RD ke lintlha tsa bohlokoa tse amang ts'ebetso ea bona lits'ebetsong tsena.Sengoliloeng sena se tla shebana le mokhoa oa tlhahlobo ea viscosity oa VAE phofo RD polymer phofo.
Viscosity e hlalosoa e le tekanyo ea khanyetso ea mokelikeli ho phalla.Bakeng sa VAE powders RD polymer powders, viscosity ke parameter ea bohlokoa e amang metsi le ho sebetsa ha metsoako ea samente.Ha li-viscosity li phahame, ho ba thata le ho feta hore phofo e kopane le metsi, e leng se etsang hore ho be le maqhubu le ho hasana ho sa fellang.Ka hona, ke habohlokoa haholo ho boloka boemo ba viscosity ea phofo ea polymer ea RD ho finyella boleng bo tsitsitseng ba sehlahisoa sa ho qetela.
Mokhoa oa tlhahlobo ea viscosity bakeng sa phofo ea VAE powder RD polymer e etsoa ho sebelisoa viscometer e potolohang.Viscometer e potolohang e lekanya torque e hlokahalang ho bilika lesela ka har'a sampole ea phofo ea polima e fanyehiloeng ka metsing.Spindle e potoloha ka lebelo le itseng mme torque e lekanngoa ka centipoise (cP).Ka mor'a moo, viscosity ea phofo ea polymer e baloa ho itšetlehile ka torque e hlokahalang bakeng sa ho potoloha spindle.
Mehato e latelang e hlalosa mokhoa oa mokhoa oa Teko ea Viscosity bakeng sa VAE Powder RD Polymer Powder.
1. Tokiso ea mohlala: Nka mohlala oa moemeli oa phofo ea polymer ea RD 'me u lekanye ho 0.1 g e haufi.Fetisetsa sampole setshelong se hloekileng, se omeletseng le se nang le tared.Ngola boima ba setshelo le sampole.
2. Hlakola phofo ea polymer: Hasanya phofo ea polymer ka metsing ho ea ka litaelo tsa moetsi.Ka tloaelo, phofo ea polymer e kopantsoe le metsi ho sebelisa motsoako o phahameng oa lebelo.Kopanya phofo ea polymer le metsi bonyane metsotso e 5 kapa ho fihlela motsoako oa homogeneous o fumanoa.Lebelo la ho kopanya le nako e lokela ho lumellana ho pholletsa le teko.
3. Tekanyo ea viscosity: sebelisa viscometer e potolohang ho lekanya viscosity ea ho emisoa ha phofo ea polymer.Boholo ba spindle le lebelo li lokela ho khethoa ho latela viscosity e lebelletsoeng ea phofo ea polymer.Ka mohlala, haeba viscosity e tlaase e lebeletsoe, sebelisa boholo bo bonyenyane ba spindle le RPM e phahameng.Haeba ho lebeletsoe viscosity e phahameng, sebelisa boholo bo boholo ba spindle le lebelo le tlaase.
4. Calibration: Pele o nka litekanyo, lekanya viscometer ho latela litaelo tsa moetsi.Sena se kenyelletsa ho beha ntlha ea zero le ho lekanya ka litharollo tse tloaelehileng tsa viscosity e tsebahalang.
5. Lekanya torque: Beha rotor ka har'a ho emisoa ha phofo ea polymer ho fihlela e qoelisoa ka ho feletseng.The spindle ha ea lokela ho ama tlase ea setshelo.Qala ho ohla spindle 'me u emetse hore torque e bale ho tsitsa.Rekota 'malo oa torque ka centipoise (cP).
6. Ikatisetsa: Bonyane litekanyo tse tharo tse ikatisang li ile tsa nkoa bakeng sa sampole ka 'ngoe le viscosity e tloaelehileng e baloang.
7. Ho hloekisa: Ka mor'a hore tekanyo e phethoe, hloekisa rotor le setshelo hantle ka metsi le sesepa.Hlatsoa ka metsi a hloekisitsoeng 'me u omelle ka hloko.
The viscosity ea RD polymer powders e angoa ke lintlha tse 'maloa tse kenyelletsang mocheso, pH le mahloriso.Ka hona, ke habohlokoa haholo ho lekanya viscosity tlas'a maemo a tloaelehileng.Hape, litekanyo tsa kamehla tsa viscosity li lokela ho nkoa ho netefatsa ts'ebetso e tsitsitseng ea li-polymer powders tsa RD.
Ka kakaretso, mokhoa oa tlhahlobo ea viscosity oa VAE powder RD polymer powder ke teko ea bohlokoa ho fumana hore na ho na le metsi le ho sebetsa ha lihlahisoa tse entsoeng ka samente.Teko e lokela ho etsoa ho sebelisoa lisebelisoa le mekhoa e tloaelehileng ho fumana liphetho tse nepahetseng le tse ka hlahisoang hape.Litekanyo tsa viscosity li lokela ho nkoa nako le nako ho netefatsa boleng ba phofo ea polymer ea RD.
