Kupuruzira nyaya pamberi pekugadzira mapepa, zvichisiya kukanganisa kukuru pakushanda kwakajairwa kwemuchina wepepa uye kunaka kwepepa. Zvinhu zvakakosha mukurova iko kudzikamisa pulp, kurova degree, uye pulp ratio.
Pulp Concentration Measurement
Kusagadzika kusungirirwa kwepulp kunogona kutungamira kune isingaenderane bepa kunaka, uye zvinogona kukonzera kuputika kwepepa uye kukanganisa zvakajairika mapepa kuita zvakanyanya. Zvinhu zvekusagadzikana kwekusagadzikana kwe pulp kusagadzikana kunogara pakuchinja kusungirirwa kwembishi pulp uye tsvina zvinhu, bhuku rekugadzirisa kugadzirisa mukurova, kuisa pfungwa uye kusanganisa, pamwe nekusagadzikana kwewhitewater system.
Shanduko muRaw Pulp Concentration
Iyo pulp inounzwa kubva kumusangano wepuping inosiyana mukusimbisa. Yekupedzisira pulp concentration ichakanganiswa kana shanduko dzinodiwa dzisina kuitwa mukutarisisa.
Concentration Adjustment muKurova
Panguva yekurohwa, pulp inopinda maitiro akaita sekuisa pfungwa, kurova, uye kusanganisa, zvinoda kugadziriswa kwekugadzirisa. Mamwe masisitimu anoshandisapulp densitymeter, asi kugadziriswa kwemaoko kunowanzoitika. Kuchinja kweconcentration kunogona kuitika nekuda kwekusaziva mushandisi, kushaikwa kwehushingi, kana kusashanda zvakanaka kwemidziyo.
Kusiyana muWaste StuffConcentration
Pepa rakatyoka zvakare rinochekwa mu hydropulper robva radzika kusvika padanho rakagadzikana risati ranyungudutswa kune inodiwa process concentration. Kana iyo tsvina yetsvina ichisiyana zvakanyanya panguva yekupera mvura uye dilution, inogona kukanganisa iyo yese pulp system.
Kusagadzikana muWhite Water Systems
Mvura chena inoshandiswa zvakare kunyungudutsa pulp kuderedza kushandiswa kwemvura uye kurasikirwa kwefiber. Kana iyo chena yemvura system isina kuenzana kana kudzvanywa kwayo uye kuyerera kusina kugadzikana, zvinokanganisa pulp dilution uye kuisa pfungwa.
Kurova Degree
Zvinhu zvinoverengeka zvinopesvedzera kurova kwe pulp, senge kudzvanywa, kutarisisa, kuyerera, nguva, tembiricha, blade mamiriro, uye hunyanzvi hwemushandisi. Kana chero nhanho ikabatwa zvisina kunaka, iyo pulp kurova mhando inokanganiswa. Kudzikamisa kurova kunonetsa pasina kuenderera mberi kwekutarisa, asi kwakakosha pakugadzikana kwemapepa.
1. Migumisiro yeDhigirii reKurova pasi
Kana kurohwa kwakanyanyisa, masvingo ekutanga uye echipiri efibers haana kuparara zvakakwana. Fiber kuzvimba, kucheka, fibrillation, uye faindi kuumbwa hakuzadzise zvinodiwa maitiro.
Izvi zvinoguma nekumhanya zvakanyanya kwemvura panguva yekugadzira, kushomeka kwefiber bonding, uye isina kuenzana pepa chimiro, ichikanganisa kufanana, simba, uye kutsvedzerera.
2. Migumisiro Yepamusoro Kurova Dhigirii
Kuwedzera kurova kunonatsiridza simba rekubatanidza asi kunoderedza avhareji urefu hwefiber uye huremu hwewebhu hunyoro.
Kurova zvakanyanya kunomhanyisa kucheka fiber, kuzvimba, uye fibrillation, zvichiita kuti mvura pawaya inyanye kuoma, kuwedzera tambo yemvura, uye kuwedzera hunyoro muwebhu nyoro.
Kuwedzera mwando kunogona kukonzera embossing kana kuwanda mabreak nekuda kwekusakwana kwepressure pressure.
Kurova kwepamusoro kunowedzerawo kuomesa shrinkage, zvichitungamira kune shanduko mukumhanya kwemarejiyo pazvikamu zvemuchina, zvichikanganisa zviyero zvemashiti, uye kuderedza simba uye kugadzikana.
Pulp Ratio
Iyo pulp reshiyo inoenderana nezvinhu zvakaita sembishi zvinhu hunhu, pulping nzira, kuita kwemuchina, uye bepa mhando uye mhando zvinodiwa. Mushure mekutarisa mamiriro ereshiyo, kunyatsotevedzera maitiro kwakakosha kudzivirira kukanganisa kwekugadzira uye kuwedzera mitengo.
Yakareba vs. Short Fiber Ratio
Chiyero chakakodzera chinokwidziridza faibha bonding, sheet kufanana, uye simba uku ichideredza mutengo nekuvandudza kushanda zvakanaka.
Kunyanya kureba fiber kunoderedza kusimba kwekubatanidza uye kunyorova kweshizha simba, zvichikonzera kutsemuka, nepo yakawandisa refu fiber isingagoneke mune zvehupfumi.
Kufunga Kwakakosha
Kemikari yehuswa pulp, ine mapfupi mafiber, gobvu maseru madziro, uye yakakwira hemicellulose zvemukati, zvinokanganisa kugadzira mapepa uye zvinokanganisa kunaka. Kudzikamisa nyaya idzi, zvemhando yepamusoro zvehurefu hwefiber zvinhu, zvakaita sedonje, huni, kana mufurakisi pulp, zvinogona kusanganiswa mukati, kunyangwe zvichidhura. Kusanganisa kwakaringana kwemafiber akareba uye mapfupi ndicho chinhu chakakosha pakuita mapepa akatsetseka, kusangana nezviyero zvemhando yepamusoro, uye kuwana mutengo wakanaka.
