Kuyerwa kweKutarisa Pulp
Kuwanda kwepulp mubhokisi remuchina kunosvika 2.5–3.5% kazhinji. Mvura inodiwa kuti pulp iderere kusvika padanho rakaderera kuti shinda dzakapararira zvakanaka uye kubviswa tsvina.
Zvemichina yefourdrinier, huwandu hwepulp hunopinda mumesh hunosvika 0.3–1.0% zvichienderana nehunhu hwepulp, hunhu hwemidziyo, uye mhando yepepa. Padanho rino, huwandu hwekusanganiswa hunoenderana nehuwandu hwepulp hunodiwa pamesh, zvichireva kuti huwandu hwakafanana hunoshandiswa pakuchenesa, kusefa, uye kugadzira pamesh.
Kuwanda kwepulp pamesh kwakaderera kusvika pa0.1–0.3% chete pamichina yemasilinda. Kuyerera kwemvura kuburikidza nekucheneswa nekusefa kwakakwira kupfuura zvinodiwa nepulp yakadaro isina kuzara zvakanyanya. Uyezve, michina yakawanda yekuchenesa nekusefa inodiwa kuti igadzirise pulp ine kuzara kwakaderera, zvichida mari yakawanda, nzvimbo yakakura, mapaipi akaomarara, uye kushandiswa kwesimba kwakawanda.
Michina yemasirinda inowanzoshandisamaitiro ekudurura ane matanho maviri,umo huwandu hwemvura hunodzikiswa kusvika pa0.5 ~ 0.6% kutanga kuti hucheneswe uye huseferwe pakutanga; wozodzikiswa kusvika pahuwandu hwakananga usati wapinda mubhokisi rekusimbisa.
Kunyungudutsa pulp kunoshandisa mvura chena kuburikidza nemesh iyo inowanzo shandiswa kuchengetedza mvura uye kudzoreredza shinda diki, zvinozadza, uye makemikari kubva mumvura chena. Kudzoreredza mvura chena kunobatsira kuchengetedza simba remuchina unoda kudziyisa pulp.
Zvinhu Zvikuru Zvinokanganisa Kuwanda Kwemapundu Akasanganiswa
Kusiyana kweKuwanda kwePulp muBhokisi Rinodzora
Kuchinja-chinja kwekugara zvakanaka kwemushonga kana kuchinja kwemushonga kunogona kukonzera kusiyana kwehuwandu hwemushonga. Kusafamba zvakanaka kweropa mumidziyo yemuchina kunogona kukonzera kusawirirana kwehuwandu hwemushonga munzvimbo dzakasiyana, zvichikonzera kusagadzikana kwakawedzerwa.
Kudzokera shure kwekurambas muKucheneswa uyekusefa
Kuraswa kubva mukucheneswa nekusefa kunowanzo dzorerwa musystem nemvura yakasanganiswa. Kusiyana kwehuwandu uye huwandu hwekuraswa uku kunoenderana nekushanda kwemidziyo yekuchenesa nekusefa uye huwandu hwemvura mumapombi ekupinda.
Kuchinja uku kunokanganisa huwandu hwemvura chena hunoshandiswa pakudiridza mvura, uye, zvakare, huwandu hwekupedzisira hwepulp. Matambudziko akafanana anogona kuitika mumasisitimu ekudzosa mvura mumatangi emuchina wemasilinda anodarika mvura.
Kusiyana kwehuwandu hwepulp hwakaderedzwa kunogona kukanganisa mashandiro emuchina wepepa uye mhando yepepa rekupedzisira. Nokudaro, zvakakosha kunyatsoongorora huwandu hwepulp nekushandisamita yekuenderana kwemvurayakagadzirwa naLonnmeterpanguva yekugadzira uye gadzirisa kupinda kwemafuta mubhokisi rinotonga kuti huwandu hwemafuta hurambe hwakagadzikana. Michina yemapepa yemazuva ano inowanzo shandisa zvishandiso zvinozvigadzira kuti:
- Gadzirisa otomatikikuwanda kwepulpkupinda mubhokisi rekutonga.
- Gadzirisa kupinda kwemari zvichibva pakuchinja kwehuremu hwepepa uyekuunganidzwa kwepulp yemusoro.
Izvi zvinoita kuti pulp ive yakagadzikana.
Mabhenefiti ekugadzirisa kugadzikana kweDiluted Pulp
Kudzora kuwanda kwemuchina wepepa wakasanganiswa kunobatsira pakushanda zvakanaka kwemuchina wepepa uye kuchengetedza mhando yepepa.
YeMichina yeSilinda
Kana pulp iine mwero wekurova wakaderera uye ichibvisa mvura nekukurumidza, huwandu hwemvura hwemukati nekunze muchikamu chemesh hunodzikira, zvichiita kuti pepa risabatanidzwe nemesh rishaye simba. Izvi zvinowedzera simba rehuwandu, zvinoderedza kuwanda kwemvura, uye zvinowedzera musiyano wekumhanya pakati pepulp nemesh, zvichiita kuti mapepa agadzire zvisina kuenzana.
Kuti izvi zviitike, kushandiswa kwemvura chena kunowedzerwa kuderedza huwandu hwemvura mu pulp, zvichiwedzera mwero wekuyerera kwemvura kusvika pamesh. Izvi zvinosimudzira musiyano wehuwandu hwemvura, zvinowedzera kuwanda kwemvura, zvinoderedza mhedzisiro yehuwandu, uye zvinoderedza musiyano wekumhanya, nokudaro zvichivandudza kufanana kwepepa.
Yemichina yeFourdrinier
Kurova kwakanyanya kunoita kuti mvura iome, kunowedzera mvura, kuwedzera hunyoro mupepa rakanyorova, uye kunotungamira pakudzvanya kana kupwanya pepa panguva yekudzvanya. Kumanikidzwa kwepepa pamuchina kunoderedza, uye kuomeswa kunowedzera, zvichikonzera zvikanganiso zvakaita sekupeta nemakwinya.
Kuti zvikunde matambudziko aya, huwandu hwemvura inoyerera muvhu hunogona kuwedzerwa nekuderedza kushandiswa kwemvura yakachena, zvichideredza matambudziko emvura inoyerera.
Kusiyana neizvi, kana mwero wekurova wakaderera, shinda dzinowanzo svetuka, uye kubuda kwemvura kunoitika nekukurumidza pamesh, zvichikanganisa kufanana kwepepa. Panyaya iyi, kuwedzera kushandiswa kwemvura chena kuderedza huwandu hwepulp yakaderedzwa kunogona kuderedza kusvetuka uye kuwedzera kufanana.
Mhedziso
Kunyungudutsa mvura ibasa rakakosha pakugadzira mapepa. Mukugadzira, zvakakosha kuti:
- Tarisa zvakanyanya uye dzora zvakanyanya shanduko dziri mu "dedulated"kuwanda kwepulpkuona kuti mashandiro aro agadzikana.
- Teererai shanduko mumhando yechigadzirwa nemamiriro ekushandauye, kana zvichidikanwa, gadzirisa huwandu hwemapundu sechishandiso chekukunda matambudziko akaita seaya ataurwa pamusoro apa.
Nekugadzirisa zvinobudirira kusanganiswa kwepulp, kugadzirwa kwakagadzikana, bepa remhando yepamusoro, uye kushanda zvakanaka zvinogona kuwanikwa.
