Cellulose ipolymer yechisikigo here kana kuti yakagadzirwa?

Serosiipolymer yechisikigo, chinhu chakakosha pamadziro esero mumiti. Ndiyo imwe yemakemikari akawanda eorganic pasi pano uye inoshanda sechinhu chekuvaka muumambo hwemiti. Patinofunga nezve cellulose, tinowanzoibatanidza nekuvapo kwayo muhuni, donje, bepa, nezvimwe zvinhu zvakasiyana-siyana zvinobva mumiti.

Maumbirwo e cellulose ane cheni refu dzemamorekuru eglucose akabatana kuburikidza ne beta-1,4-glycosidic bonds. Cheni idzi dzakarongwa nenzira inodzibvumira kuumba maumbirwo akasimba, ane fibrous. Kurongeka kwakasiyana kwecheni idzi kunoita kuti cellulose ive nehunhu hwayo hunoshamisa hwemakanika, zvichiita kuti ive chinhu chakakosha mukupa rutsigiro rwemaumbirwo kumiti.

Maitiro ekugadzira cellulose mumiti anosanganisira enzyme inonzi cellulose synthase, iyo inopomesa mamorekuru eglucose kuita cheni refu uye inoaburitsa mumadziro esero. Maitiro aya anoitika mumhando dzakasiyana dzemasero emiti, zvichibatsira mukusimba uye kuomarara kwematishu emiti.

Nekuda kwekuwanda kwayo uye hunhu hwayo hwakasiyana, cellulose yawana mashandisirwo akawanda kunze kwebasa rayo muzvirimwa. Maindasitiri anoshandisa cellulose kugadzira mapepa, machira (akadai sedonje), uye mamwe marudzi emafuta ehupenyu. Pamusoro pezvo, zvinhu zvinobva mucellulose zvakaita se cellulose acetate uye cellulose ethers zvinoshandiswa muzvigadzirwa zvakasiyana-siyana, zvinosanganisira mishonga, zvekudya, uye machira.

Panguva iyoseluloseIyo pachayo ipolymer yechisikigo, vanhu vakagadzira maitiro ekuichinja nekuishandisa nenzira dzakasiyana-siyana. Semuenzaniso, kurapwa nemakemikari kunogona kushandura hunhu hwayo kuti ive yakakodzera kushandiswa kwakanangana. Zvisinei, kunyangwe mumhando dzakagadziriswa, cellulose inoramba iine mavambo ayo echisikigo, zvichiita kuti ive chinhu chinoshandiswa zvakasiyana-siyana uye chinokosha mumamiriro ese echisikigo neemainjiniya.
