Cellulose ethers inoita basa rakakosha muindasitiri yemapepa, ichibatsira mune ese maficha ekugadzira mapepa nekuvandudza kunaka uye kuita kwezvigadzirwa zvemapepa.
1. Nhanganyaya kune cellulose ether:
Cellulose ethers iboka remvura-inonyungudika mapolima anobva ku cellulose, yakasikwa polymer inowanikwa muchirimwa sero madziro.Nzvimbo huru ye cellulose ethers ihuni pulp, uye inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, kusanganisira mishonga, chikafu, kuvaka, uye kunyanya indasitiri yemapepa.
2. Zvinhu zve cellulose ether:
a.Kunyungudika kwemvura:
Chimwe chezvinhu zvakakosha zve cellulose ethers ndiko kunyungudika kwemvura.Iyi pfuma inoita kuti vapararire nyore nyore mumvura, zvichiita kuti vabatanidzwe mu pulp.
b.Kukwanisa kugadzira firimu:
Cellulose ethers vane maitiro ekugadzira firimu anobatsira kuvandudza nzvimbo dzepamusoro uye kuvandudza huwandu hwese hwepepa.
c.Kuwedzera uye kubatanidza:
Cellulose ethers inoshanda seyakakora, ichiwedzera viscosity ye pulp.Iyi ficha inobatsira kudzora kuyerera kwe pulp panguva yekugadzira mapepa.Mukuwedzera, ivo vanoita semadhesi, vachikurudzira kusungirirwa kwemafiber mupepa.
d.Yakagadzikana:
Aya ether anoratidza kugadzikana pasi pemamiriro akasiyana-siyana, kusanganisira tembiricha uye pH shanduko, zvichibatsira kuvandudza kuvimbika kwavo mukugadzira mapepa.
3..Basa re cellulose ethers muindasitiri yemapepa:
a.Kuchengetedza uye kunatsiridza kwemvura:
Cellulose ethers inozivikanwa nekugona kwavo kukwidziridza kuchengetwa kwe pulp uye mvura panguva yekugadzira mapepa.Izvi zvinovandudza mapepa flatness uye kuderedza kushandiswa kwemvura.
b.Kusimbisa:
Kuwedzerwa kwe cellulose ethers kunovandudza masimba epepa, kusanganisira kusimba kwesimba, kuputika simba uye kuramba kubvarura.Izvi zvinonyanya kukosha pakugadzira mapepa emhando yepamusoro akakodzera kushandiswa kwakasiyana-siyana.
c.Surface size:
Cellulose ethers inoshandiswa mukuumbwa kwepamusoro saizi kubatsira kugadzira nzvimbo yakatsetseka, yakafanana pabepa.Izvi zvinowedzera kudhindwa uye kutaridzika kwechigadzirwa chekupedzisira.
d.Kudzora kutorwa kweinki:
Mukudhinda maapplications, cellulose ethers inobatsira kudzora kunyura kweinki, kudzivirira kuwandisa-kupararira uye kuve nechokwadi chekudhinda kunaka.
e.Kudzora kwepepa porosity:
Cellulose ethers inobatsira kudzora porosity yepepa nekukanganisa kuumbwa kwepepa chimiro.Izvi zvakakosha kune maapplication akadai sefirita bepa.
f.Kuchengetedza kunobatsira mumafiller uye additives:
Cellulose ethers inoshanda sezvibatsiro zvekuchengeta zvekuzadza uye zvimwe zvinowedzera mukuita mapepa.Izvi zvinovimbisa kuti izvi zvinosanganiswa zvinonyatso chengetwa mukati mechimiro chepepa.
4. Kushandiswa kwe cellulose ether muzvigadzirwa zvemapepa:
a. Bepa rekudhinda nekunyora:
Cellulose ethers inoshandiswa zvakanyanya mukugadzirwa kwekudhinda nekunyora mapepa kuti iwane yakanaka kudhinda mhando, kutsvedzereka uye pamusoro pezvivakwa.
b.Pepa rekupeta:
Mumapepa ekurongedza, cellulose ethers inobatsira kuwedzera simba, kuve nechokwadi chekuti bepa rinogona kumira kuoma kwekurongedza uye kutumira.
c.Tissue:
Cellulose ethers inopa pepa rechimbuzi kupfava kwayo, simba uye kunwa.Izvi zvimiro zvakakosha kune kumeso kwechiso, bepa rechimbuzi uye zvimwe zvigadzirwa zvematishu.
d.Special bepa:
Mapepa ehunyanzvi, senge bepa rekusefa, bepa rekuvhara magetsi, uye bepa rekurapa, kazhinji anosanganisa cellulose ether kuti asangane nezvinodiwa zvekushanda.
5. Mafungiro ezvakatipoteredza:
a.Biodegradability:
Cellulose ethers inowanzo parara, zvinoenderana neindasitiri yemapepa iri kukura kudiwa kwemaitiro ane hushamwari uye anoenderera mberi.
b.Renewable energy:
Sezvo cellulose ethers inotorwa kubva muhuni pulp, chigadziro chinogona kuvandudzwa, kushandiswa kwavo kunobatsira kusimba kwemaitiro ekugadzira mapepa.
Cellulose ethers inobata basa rakawanda muindasitiri yemapepa, inobata zvese zvekugadzira mapepa uye kubatsira kugadzira emhando yepamusoro zvigadzirwa zvemapepa.Kunyungudika kwavo kwemvura, kugona kugadzira firimu, uye zvimwe zvinhu zvakasarudzika zvinoita kuti zvive zvakakosha zvekuwedzera mukugadzira mapepa.Sezvo indasitiri yemapepa ichiramba ichishanduka, kukosha kweselulosi ether mukuvandudza kunaka kwepepa, kuita uye kusimba kunogona kuenderera mberi nekukura.
