Ukuphonononga iPolyDADMAC

Ukuphonononga ubudlelwane phakathi kobunzima beMolekyuli, i-Viscosity, umxholo oqinileyo, kunye noMgangatho wePolyDADMAC

I-PolyDADMAC (eyaziwa nangokuthi "i-polydiallyl dimethyl ammonium chloride") i-polymer ye-cationic esetyenziswa kwiinkqubo zokunyanga kwamanzi. Ixabiswa ngenxa ye-flocculation yayo emihle kunye nemiphumo ye-coagulant. Njengomthengisi kunye nomthengisi weekhemikhali zokunyanga amanzi, kubalulekile ukuqonda ubudlelwane phakathi kobunzima bemolekyuli, i-viscosity kunye nomxholo oqinileyo wePolyDADMAC kunye nomgangatho wemveliso. Kweli nqaku, siza kuphonononga ulungelelwaniso phakathi kwezi zalathisi kunye nendlela yokukhetha iimveliso ezikumgangatho ophezulu ezifanelekileyo kuwe.

Ubunzima be-molecular, i-viscosity kunye nomxholo oqinileyo wePolyDADMAC ziiparamitha eziphambili ezichaphazela umphumo wayo. Zinxulumene. Oku kulandelayo yinkcazo eneenkcukacha zabo kunye nenkcazo eneenkcukacha zobudlelwane babo:

1. Ubudlelwane

Ubunzima bemolekyuli bubhekisa kumndilili wobude bePolyDADMAC polymer chain.

Ubunzima beemolekyuli eziphakamileyo ngokubanzi zithetha amatyathanga epolymer amade, anokuphucula amandla e-flocculation yePolyDADMAC. Kwaye amanqanaba aphezulu eemolekyuli abonelela ngokubanzi ngeziphumo zokuvala, ezivumela amasuntswana amancinane emanzini ukuba adityaniswe kunye. Inokuphucula iziphumo zokunyanga amanzi.

Nangona kunjalo, ubunzima obukhulu be-molecular bunokukhokelela kwi-viscosity egqithisileyo, echaphazela ukusebenza.

Ubunzima bemolekyuli luphawu olubalulekileyo lomgangatho wePDDMAC kuba ichaphazela ngokuthe ngqo umphumo wesicelo sayo.

I-PDADMAC ye-molecular weights iqhelekile ukusuka kwi-50,000 ukuya kwi-700,000Da, kunye neemveliso ezinobunzima be-molecular ultra-high kufuneka max ngaphandle kwe-3,000,000Da.

2. I-Viscosity

I-Viscosity ibhekisela ekuchaseni isisombululo sePolyDADMAC ukuhamba.

Ngokuqhelekileyo i-viscosity yi-80-12,000mPa.s, kwaye kukho i-PolyDADMAC ephezulu ye-viscosity ene-viscosity enkulu kune-100,000. I-Viscosity inxulumene ngokusondeleyo nobunzima be-molecular, kwaye ubunzima beemolekyuli eziphezulu zikhokelela kwi-viscosity ephezulu. Kwaye i-viscosity ichaphazela i-solubility kunye ne-dispersibility ye-PDADMAC, kunye nokusebenza kwayo ekusebenzeni kwizicelo. Ukuba i-viscosity iphezulu kakhulu, i-viscosity ephezulu iya kubangela ubunzima bokusebenza (ukudlulisa kunye nokunciphisa, njl.) I-Viscosity yiparameter ebalulekileyo yokulinganisa umgangatho we-PDADMAC kuba ibonisa ubunzima bayo be-molecular kunye nokusebenza kwesicelo., ngelixa i-low-viscosity ye-PolyDADMAC ine-fluidity enhle kwaye kulula ukuyipompa.

3. Umxholo oqinileyo

Umxholo oqinileyo ubhekisela kwipesenti yobunzima bepolymer kwisisombululo sePolyDADMAC.

Umxholo oqinileyo ophezulu uthetha ukunciphisa iindleko zokugcina kunye nomthwalo. Nangona kunjalo, ukuba imveliso enobunzima obuphezulu bemolekyuli ilungiswa njengesisombululo se-40%, ayinakugalelwa nakwigubu.

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

Ngokuqhelekileyo, umxholo oqinileyo wePolyDADMAC esiyithengisayo malunga ne-40%. Sikwanayo neminye imiba yomxholo oqinileyo.

Ungajonga iinkcazo eneenkcukacha yemveliso yePolyDADMACkwiinkcukacha ezithile kunye nezalathi ezineenkcukacha zePolyDADMAC.

Ubudlelwane phakathi kwabo:

Ubunzima bemolekyuli kunye ne-viscosity:

Ngomxholo oqinileyo ofanayo, ukuphakama kwe-molecular weight, i-viscosity enkulu.

Ubukhulu be-molecular weight, buphezulu i-viscosity.

Umxholo oqinileyo kunye ne-viscosity:

Kubunzima obufanayo bemolekyuli, ukuphakama komxholo oqinileyo, ngakumbi i-viscosity.

Ubunzima bemolekyuli, umxholo oqinileyo, kunye nokusebenza:

Kumxholo othile oqinileyo, ukuphakama kwe-molecular weight, ngcono umphumo, kodwa i-viscosity iya kwanda.

Ungayikhetha njani iPolyDADMAC ekufaneleyo

I-viscosity enengqiqo: qinisekisa ukuguquguquka, ukunyibilika lula, kunye nokusebenza kakuhle kwe-flocculation.

Ukuba ufuna ukufumana umthengisi omtsha ukuthenga i-PolyDADMAC, ngoko kuqala kufuneka unqume ubunjani bakho bomgangatho wamanzi ukuze umthengisi wakho akuncede ukhethe imodeli engcono. Okanye unokuxelela umthengisi uphawu kunye nemodeli yePolyDADMAC oyisebenzise ngaphambili. Okanye ungathumela iPolyDADMAC yakho esele ikhona kumthengisi wakho omtsha kwaye ubavumele bakuncede uhlalutye kwaye ukhethe. Uvavanyo lwesampula yePolyDADMAC entsha ibaluleke kakhulu, kwaye kufuneka wenze uvavanyo ngononophelo ukufumanisa ukuba imodeli ikulungele ngakumbi.

Njengengcaliumboneleli wePolyDADMAC, sinokukubonelela ngeenkonzo zokukhetha kwaye sikuthumelele iisampuli zamahhala. Ukuba unazo naziphi na iimfuno, nceda uqhagamshelane nathi. Siza kukuthelekisa noyena mphathi wentengiso yobuchwephesha ukuze sikukhonze.
