Sei uchidaroDispersant NNOkushanda?
Dispersant NNOmamorekuru ane mapoka anchoring uye zvikamu zvinodzikamisa. Basa reboka rekumisa ndere kupa simba rakakwana rinosunga kune pigment filler particles. Dispersant molecules haadonhe kubva pamusoro pezvimedu, zvinova zvinodikanwa kuti dispersant ishande. Basa rechikamu chekudzikamisa ndechekudzikamisa pigment aggregate particles akaparadzirwa ne mechanical simba kuburikidza ne electrostatic repulsion uye spatial resistance muchikamu chemvura kudzivirira zvimedu kubva pakuungana.
Mune organic solvents, apo iyo yakagadzikana chikamu cheDispersant NNOinodzikamisa iyo yakapararira pigment particles nekupikiswa kwenzvimbo, apo kuparadzaniswa kwezvimedu zvinopararira kudiki pane saizi yeketani yekunyungudutsa, ketani yekunyungudutsa inosvina mumwe nemumwe uye entropy inoderera. Mumvura, ionization inoitika yakatenderedza mapoka eionic kuti aumbe kaviri layer, uye electrostatic repulsion inodzivirira particle agglomeration. Kana isiri-ionized polyether yakagadzikana, polyether inodzikamisa yakapararira pigment particles ne spatial resistance.
Muchigadziro chekugadzira mapepa uye mapepa, nhamba huru yemapepa emakemikari anoparadzira anodiwa kuti agadzirise matambudziko ekupararira, kuchengetedza, filtration nezvimwe zvakadaro. Kuwedzera makemikari anoparadzira kune pulp kunogona kuderedza fiber mhepo uye kuita bepa rakatsetseka uye kuita kwakanaka. Kazhinji, makemikari ekuwedzera anoshandiswa mukusefa, sekuyerera kweAIDS, mafirita, anoparadzira, anosimbisa maajenti, anopupuma, zvinodzivirira, biological enzymes, etc. Muchirongwa ichi chekugadzirira, mamwe ari ega, mamwe anosanganiswa, anoshandira pamwe. kuvandudza kunaka kwepeji, kunyatsovandudza kugadzirwa kwekugadzira, kuderedza mutengo wekugadzira.
Fiber ndicho chinhu chakakosha chinokanganisa kunaka kwepepa mukugadzira mapepa. Kungofanana nefiber yakareba kusapindirana kwakashata, kugadzira zvinowedzera, mafirita uye zvichingodaro kure kubva kune mumwe nemumwe, uye zvino zvakaoma kuwana yunifomu kuita, iro rakakodzera simba repepa. Nekudaro, nekuwedzera kweakakodzera disperant, pamusoro pezvimedu zvimedu zvinogona kuumba bimolecular chimiro, uye hunyoro hwehunyoro hwezvikamu zvakasimba hunogona kuvandudzwa. Mamwe akanaka fiber dispersants anoda imwe pyrolytic zvivakwa, izvo zvinogona kuvandudza kupararira kwekubudirira nekuwedzera kwekushisa. Wobva waderedza viscosity ye pulp, uvandudze pepa repamusoro uye kupfava.
