Polwandacrrylambideinowaniswazve inoshandiswa muindasitiri yepepa. Polwandacrrylabide (PAM), sePoluble-Soluble Polymer, ine ruzha rwakanyanya, rwakakora, kupararira uye zvimwe zvivakwa. Ichaiswa kune akati wandei maitiro akasiyana nemabasa akasiyana. Muindasitiri yepepa, Pam anoita basa risingabvumirwe. Izvo zvakaunza zvakakosheswa zvehupfumi zvehupfumi kune iyo indasitiri yepepa nekuvandudza zvinhu zve pulp uye kuwedzera kushanda kwekushanda kwemishini yepepa. Chinyorwa ichi chichakurukura zvakadzama kushandiswa kwePolwacrylamide mupepa kugadzirwa uye zvarinoita pakuvandudza kushanda kwekugadzira.
Zvivakwa zvekutanga uye zvinoshanda zvePolwacrrylambide
Polwacrylakude yakakwira mholocular polymer inogona kukamurwa kuita nonitic, anonic, cationic uye amphoteric mhando zvinoenderana nezvivakwa zvayo. Pam painopera mumvura, uye chimiro chemoyo mapofu chinoita kuti iite mabasa akanaka kwazvo senge fliveculation, kuremedza, kubatsirwa, uye rubatsiro rwekufa. Mune iyo yepepa indasitiri, polyacrrylambide inonyanya kushandiswa mune zvinotevera zvinhu:
1. Ramba Rubatsiro:
Pam mamorekuru vane tambo refu uye inogona kushambidzwa pamusoro pemakona uye mafirita ekugadzira mabhiriji. Nokudaro vachivandudza huwandu hwenhamba dzevhifiresi uye machira papepa reb. Deredza fiber kurasikirwa mumvura chena uye kuderedza kurasikirwa kwezvinhu. Nekuwedzera huwandu hwenhamba dzevirahwe uye machira, mapepa emapepa emuviri akadai sekutsamwa, kudhinda, uye simba rinogona kuvandudzwa.
2. Filter Aid:
Kuvandudza mashandiro ekunyanyisa kwePulp, kumhanyisa mvura yekufamba kwemvura uye kuderedza kushandiswa kwesimba.
3. Floculant:
Simudza SLUDGE DEHYDRATTRARY: PAMASIKI KUTI DZIDZO DZESVONDO DZINOGARA, DZIMWE DZIMWE DZIMWE DZESVONDO DZINOGADZIRA DZIMA, DZINOGARA DZINOGARA DZINOGADZIRA UYE KUDZVANYA KWEMAHARA.
Kuvandudza Mhando Yemvura: Pam inogona kubvisa zvinokwanisika kudzikisira solids uye organic zvinhu mumarara, kuderedza bhodhi uye cod mumarara, kuvandudza mhando yemvura, uye kuderedza kusvibiswa kwezvakatipoteredza.
4. kuparadzira:
Dzivirira Fiber Agglomoration: PAM inogona kudzivirira zvinobudirira fiber Agglomeration mu pulp, kugadzirisa iyo kusaenzana kwe pulp, uye kugadzirisa iyo mhando yepepa.
Kushandiswa kwePolwacrylwide muPepa rePapermaking Technology
1. PULP Kugadzirira Stage
Munguva yePulp Kugadzirira Kugadzirisa, Fully Fibers uye mafirita anorasikirwa nyore nyore neine tsvina, ichikonzera kusagadzikana marara uye kusvibiswa kwezvakatipoteredza. Uchishandisa cationic polyacrrylirryode seyakaitwa nerondedzero inokwanisa kubata uye kugadzirisa madiki madiki uye mafirita ari mupururu kuburikidza nemabhadharisi ekugadzira uye ekutora. Izvi hazvingori kungodzora kurasikirwa kwemafambiro, asi zvakare kunoderedza kuremerwa kwekurapa kwekurapa.
2. Pepa remuchina rakanyorova mugumo system
Mupepa remuchina rakanyorova kupera system, kukurumidza kushatirwa ndiyo kiyi yekuvandudza kugadzirwa kwekugadzira. Anonic kana isonionic Polycrylwide inogona kushandiswa seyakaitwa rubatsiro kuti iite kuti zvive nyore kuti mvura ipukunyuke kubva kuFiber network network nekuvandudza iyo flecolation pakati pemitsara pakati pemiti. Iyi process inokwenenzvera nguva yekushambadzira nguva iyo ichidzora simba rekushandisa mukati mechikamu chekuoma.
3. Papermaking nhanho
Semunhu anoparadzira, polycrylwide anogona kudzivirira zvinobudirira fiber fleculation uye kuvandudza kufanana uye kusekwa kwepepa. Nekunyatsosarudza kuremerwa nehuremu uye kubhadharisa kuremerwa kwePam, zvivakwa zvepanyama zvebepa rakapera, sesimba rakazara uye rinobvaruka, rinogona zvakare kugadzirwa. Mukuwedzera, polwacrylwide inogona zvakare kuvandudza kuunganidza mari yepepa rekuchinjisa uye kuita kuti kuitisa kuita kwepepa kuri nani.
Zvakanakira zvakakosha zvePolwacrylwide mukuvandudza mari yekugadzira
1. Deredza kurasikirwa kwezvinhu
Iko kushandiswa kweAidnion AIDS kunokonzeresa zvinovandudza mwero wetsiva kwemapepa akanaka uye mafirita muPulp, anoderedza kuputika kwemidziyo, uye anochengetedza zvakananga mari yekugadzira.
2. Simudza Up iyo Dehydration Process
Nhungamiro yeFilter AIDS inoita iyo dewatering maitiro anoshanda zvakanyanya, nekudaro achiwedzera iyo yemushini yemuchina inoshanda uye kupfupisa kutenderera kwekugadzira. Izvi hazvingori kungowedzera chete kumira-wega kugadzirwa kugona, asi zvakare kunoderedza simba rekushandisa.
3. Deredza kutambudzika kwekurapa kwekurapa
Nekuvandudza mari yekuuraya, polycrylubation inogona kuderedza zvinobudirira zviri mukati mekumiswa nzvimbo mumarara, kuderedza kutakura nzvimbo dzekurapa kubva kunobva uye kuderedza mari yekudzivirira yemabhizimusi emabhizimusi.
4. Kuvandudza Pepa Unhu
Kushandiswa kwekuparadzira kunoparadzira fiber yepepa kwunifomu, kwakanyanya kunovandudza zvivakwa zvemuviri uye zvinooneka zvebepa, uye zvinowedzera kukwikwidza kwemusika kwechigadzirwa.
Zvinhu zvinokanganisa iyo yekushandisa mhedzisiro yePolwacrylamide
Kuti upe izere nekutamba nekuita kwePolwacrylwide, zvinotevera zvinhu zvinoda kutariswa pane:
1. PAM modhi kusarudzwa
Maitiro akasiyana emapepa uye mapepa emhando idzo dzinosiyana zvinodiwa kuti uremu hwemulecular uremu uye kubhadharisa density ye pam. Yakakwira Molecular uremu Pam yakakodzera kuremerwa neFlet rubatsiro, nepo yakaderera molecular uremu Pam inokodzera kuparadzaniswa.
2. Kuwedzera huwandu uye kuwedzera nzira
Huwandu hwePam hunowedzerwa hunofanirwa kuve hwakanyatso kudzorwa. Mari yakawandisa inogona kukonzera kukanganisa kwakashata, sekukanganisa kuita kwemisha kana kuwedzera kwemitengo yekugadzira. Panguva imwecheteyo, nzira yakafanana yakapararira yekuwedzera inofanirwa kushandiswa kudzivisa kuunganidzwa kwenzvimbo iyo inobata mhedzisiro.
3. Prooms mamiriro
Tembiricha, Ph uye mamiriro emvura zvese zvinokanganisa pam performance. Semuenzaniso, cationic Pam inoshanda zvakanyanya mune isina kwayakarerekera kune zvishoma acidic mamiriro, nepo anionic Pam yakakodzera kune yakakodzera nzvimbo yeAlkaline.
Semunhu anoshanda-akawanda anoshanda muindasitiri yemapepa, polyacrylwide anotora basa rakakosha mukuvandudza mari yekugadzira, kuderedza mari yekugadzira uye nekuchengetwa kwayo Mune zvinoshandiswa zvinoshanda, makambani anofanirwa kusarudza zvine musoro uye opeta mamiriro ekushandiswa ePAM kubva pane yavo yekugadzirisa maitiro uye inoda kuzadzisa zvakanaka zvakanakira zvehupfumi uye zvakatipoteredza.
