Ukuhlola iPolyDADMAC

Ukuphonononga Ubudlelwane Phakathi Kobunzima BeMolekyuli, Ubunzima, Umxholo Oqinileyo, kunye Nomgangatho wePolyDADMAC

I-PolyDADMAC (ekwaziwa ngokuba yi-"polydiallyl dimethyl ammonium chloride") yi-cationic polymer esetyenziswa kwiinkqubo zonyango lwamanzi. Ixatyiswa ngenxa ye-flocculation yayo elungileyo kunye nemiphumo ye-coagulant. Njengomthengisi kunye nomsasazi weekhemikhali zonyango lwamanzi, kubalulekile ukuqonda ubudlelwane phakathi kobunzima beemolekyuli, i-viscosity kunye nomxholo oqinileyo we-PolyDADMAC kunye nomgangatho wemveliso. Kweli nqaku, siza kuhlola ulwalamano phakathi kwezi mpawu kunye nendlela yokukhetha iimveliso ezikumgangatho ophezulu ezifanelekileyo kuwe.

Ubunzima bemolekyuli, i-viscosity kunye nomxholo oqinileyo wePolyDADMAC ziiparameter eziphambili ezichaphazela isiphumo sayo. Ziyahambelana. Oku kulandelayo yinkcazo eneenkcukacha zazo kunye nenkcazo eneenkcukacha yolwalamano lwazo:

1. Ulwalamano

Ubunzima be-molecular bubhekisela kubude obuqhelekileyo be-PolyDADMAC polymer chain.

Ubunzima obuphezulu beemolekyuli buthetha imixokelelwane emide yeepolymer, enokuphucula amandla okushukuma kwePolyDADMAC. Kwaye ubunzima obuphezulu beemolekyuli bubonelela ngemiphumo ethile yokudibanisa, okuvumela amasuntswana amancinci emanzini ukuba adityaniswe. Ingaphucula iziphumo zonyango lwamanzi.

Nangona kunjalo, ubunzima obukhulu kakhulu be-molecular bunokubangela i-viscosity egqithisileyo, nto leyo echaphazela ukusebenza.

Ubunzima bemolekyuli luphawu olubalulekileyo lomgangatho wePDADMAC kuba luchaphazela ngokuthe ngqo isiphumo sokusebenza kwayo.

Ubunzima beemolekyuli zePDADMAC buhlala buqala kwi-50,000 ukuya kwi-700,000Da, kwaye iimveliso ezinobunzima beemolekyuli obuphezulu kakhulu kufuneka zifikelele kwi-3,000,000Da.

2. Ukuxinana

I-Viscosity ibhekisa ekuchaseni kwesisombululo sePolyDADMAC ukuhamba.

Ngokwesiqhelo i-viscosity yi-80-12,000mPa.s, kwaye kukwakho ne-PolyDADMAC ene-viscosity ephezulu ene-viscosity engaphezulu kwe-100,000. I-Viscosity inxulumene ngokusondeleyo nobunzima be-molecular, kwaye ubunzima be-molecular obuphezulu bubangela i-viscosity ephezulu. Kwaye i-viscosity ichaphazela ukunyibilika kunye nokusasazeka kwe-PDADMAC, kunye nokusebenza kwayo kwizicelo. Ukuba i-viscosity iphezulu kakhulu, i-viscosity ephezulu iya kubangela ubunzima bokusebenza (ukudlulisa kunye nokuxuba, njl.njl.) I-Viscosity yiparameter ebalulekileyo yokulinganisa umgangatho we-PDADMAC kuba ibonisa ubunzima bayo be-molecular kunye nokusebenza kwesicelo., ngelixa i-PolyDADMAC ene-viscosity ephantsi inokuguquguquka okuhle kwaye kulula ukuyipompa.

3. Umxholo oqinileyo

Umxholo oqinileyo ubhekisa kwipesenti yobunzima bepolymer kwisisombululo sePolyDADMAC.

Umxholo ophezulu oqinileyo uthetha ukunciphisa iindleko zokugcina kunye nokuthutha. Nangona kunjalo, ukuba imveliso enobunzima obukhulu kakhulu be-molecular ilungiselelwe njengesisombululo se-40%, ayinakuthululwa nakwidrama.

Umxholo oqinileyo wePolyDADMAC yi-10% okanye i-50%, oko kukuthi, umlinganiselo wezinto ezisebenzayo kwisisombululo

Ngokwesiqhelo, umxholo oqinileyo wePolyDADMAC esiyithengisayo umalunga ne-40%. Sikwanazo nezinye iinkcukacha zomxholo oqinileyo.

Ungajongainkcazo eneenkcukacha zemveliso yePolyDADMACkwiinkcukacha ezithile kunye nezibonakaliso ezineenkcukacha zePolyDADMAC.

Ulwalamano phakathi kwabo:

Ubunzima beemolekyuli kunye ne-viscosity:

Kwimixholo efanayo eqinileyo, ubunzima bemolekyuli buphezulu, kokukhona i-viscosity iba nkulu.

Okukhona ubunzima bemolekyuli bukhulu, kokukhona i-viscosity iphezulu.

Umxholo oqinileyo kunye nokuqina:

Kubunzima obufanayo beemolekyuli, okukhona umxholo oqinileyo uphezulu, kokukhona i-viscosity iba nkulu.

Ubunzima be-molecular, umxholo oqinileyo, kunye nokusebenza:

Kwisiqulatho esithile esiqinileyo, okukhona ubunzima beemolekyuli buphezulu, kokukhona isiphumo singcono, kodwa i-viscosity iya kwanda.

Indlela yokukhetha iPolyDADMAC ekufaneleyo

Ukuqina okufanelekileyo: qinisekisa ukunyibilika, ukunyibilika lula, kunye nokusebenza kakuhle kwe-flocculation.

Ukuba ufuna umthengisi omtsha ukuze uthenge iPolyDADMAC, kufuneka uqale umisele umgangatho wamanzi akho ukuze umthengisi wakho akuncede ukhethe imodeli engcono. Okanye ungaxelela umthengisi uhlobo kunye nomzekelo wePolyDADMAC owawusebenzisa ngaphambili. Okanye ungathumela iPolyDADMAC yakho ekhoyo kumthengisi wakho omtsha kwaye ubavumele bakuncede uhlalutye kwaye ukhethe. Uvavanyo lwesampulu yePolyDADMAC entsha lubaluleke kakhulu, kwaye kufuneka wenze uvavanyo ngononophelo ukuze ubone ukuba imodeli ikulungele na.

Njengomsebenzi oqeqeshiweyoUmthengisi wePolyDADMAC, singakunika iinkonzo zokukhetha kwaye sikuthumelele iisampulu zasimahla. Ukuba unayo nayiphi na imfuno, nceda unxibelelane nathi. Siza kukunxibelelanisa nomphathi wentengiso ochwephesha kakhulu ukuze akuncede.
