I-Bulk Density ye-Paper Pulp
I-Lonnmeteriklame futhi yathuthukisa izinsiza zokulinganisaukuminyana ngobuningi be-pulp yephepha, ugologo omnyama notshwala obuluhlaza. Kuyenzeka ukunquma ukuminyana kwezingxenye ezincibilikisiwe noma ezingancibilikisiwe ngemitha yokuminyana eyodwa efakwe kulayini. Sinikeza izixazululo zokuminyana kanye nesilinganiso sokuhlushwa kwezicelo ezinjengotshwala obumnyama, ama-pulps wephepha ophuzo oluluhlaza. Ngaphezu kwalokho, amamitha we-pulp density ayakwazi ukukala ukuminyana kodaka lomcako uma kungenazinhlayiya ezinosayizi omkhulu kanye nenqwaba yamabhamuza.
Kungani Udinga Ukulinganiswa Okuqhubekayo Kokuminyana?
I-pulp engalinganiekwenzeni iphepha kuletha izingozi ezingaba khona kwikhwalithi engazinzile yemikhiqizo yokugcina futhi kwenyuse izindleko zokwenza iphepha. I-pulp yephepha iqukethe ukumiswa kwe-fiber emanzini ngokulinganayo. Ukungafanani kokuminyana kunomthelela kuyo yonke inqubo yokwenza iphepha.
Ukuvumelana okuguquguqukayoye-pulp ishiya izinguquko zayo ze-viscosity nezinga lokugunda, okungeza olunye ungqimba lobunkimbinkimbi esilinganisweni esiqhubekayo sokuminyana. Ukungahambi kahle kuyanda ngenxa yesizathu somoya oboshiwe, ohlanganisa amabhamuza engxubeni, okubangela ukufundwa okungamanga futhi kubukela phansi ukunemba.
Izindlela zendabuko ezisetshenziselwa ukulinganisa ukuminyana zivame ukutholakala ngokunemba lapho kushintshwa imisebenzi. Isibonelo, izindlela ze-gravimetric azifanele ukuqapha okuqhubekayo ngenxaimvelo edinga abasebenzifuthiukuba sengozini yamaphutha esampula.
Amaphuzu Wokulinganisa Kunqubo Ye-Pulp Yephepha
Thola izinkomba kulo mdwebo ongenhla ekwenzeni iphepha, kunamaphuzu ayisikhombisa okufaka imitha yokuminyana kwamakhemikhali ukuze kusetshenziswe inqubo ngokugcwele. Basebenza ezicini ezilandelayo:
1. Inqubo yokuncibilika kotshwala obumnyama emanzini;
2. Ukuminyana kotshwala obuluhlaza noma ukuqapha ukugxila;
3. Ukuminyana kotshwala obumhlophe noma ukuqapha ukugxilisa ingqondo;
4. Ukuminyana kwe-lime slurry noma ukuqapha ukugxila;
5. Ukuminyana kotshwala obumnyama obubuthakathaka noma ukugxilisa ingqondo.
Inqubo ye-kraft iguqula izinkuni zibe yi-pulp yokhuni, lapho uphuzo olumnyama noma utshwala obuchithiwe bukhiwa ngokhuni. Bese kugaywa utshwala obumnyama kuze kube uphuzo oluluhlaza. Ngaphezu kwalokho, kungashintshwa kube utshwala obumhlophe ngokungeza ubisi lwe-lime ukuze lululame. Ngakho-ke, ukuminyana noma ukulawulwa kokugxilisa ingqondo kumaphuzu okulinganisa angaphezulu kubalulekile ekulawuleni ikhwalithi nokulawulwa kwezindleko.
Kunconyiwe Density Meter
I-Lonnmeterimitha ye-pulp densityiyindlela ekahle yokuqapha ukuminyana okuqhubekayo ekulawuleni ukunemba, enikeza ukufundwa okunembile kuma-opharetha ngesikhathi sangempela. Ukufundwa kwayo okunembayo kungafinyelela ku-±0.002g/cm³, futhi ububanzi bokulinganisa buwela ku-0-2 g/cm³. Okukhiphayo kulethwa ngesignali engu-4-20 mA. Ukuze abasebenzisi bokugcina bakwazi ukulungisa amapharamitha okucubungula ngokushesha ukuze bathole ikhwalithi ezinzile nokuvumelana, njengokwengezwa kwe-pulp yephepha, okuqukethwe kwamanzi kanye nezinga lokuyaluza.
Ukwengeza, ukuqapha kwesikhathi sangempela kwe-pulp yephepha kuyinzuzo ukuthola okungavamile ekucutshungulweni, njengokungaguquguquki okuguquguqukayo, ukungafani kwe-pulp yephepha kanye nokuwohloka kwemishini. Khona-ke ezinye izinyathelo zingathathwa ngokushesha ukuze kugwenywe ukulahlekelwa komkhiqizo kanye nemikhiqizo engenamsebenzi.
Xhumana nonjiniyela wethu ukuze uthole imininingwane eyengeziwe mayelana nemitha yokuminyana kwe-pulp, futhi ungathola iziphakamiso zodwendwe mayelana nokukhetha imitha yokuminyana esemgqeni efanelekile. Cela isicaphuna samahhala manje!
