Isiphumo se-selsulose ether kwiplastiki yeplastiki yeplastiki yodaka

1. Imvelaphi yophando yesiphumo seI-Selersese EtherKwiplastiki yeplastiki yeplastiki yodaka

Udaka luhlobo lwezinto ezisetyenziswayo kwiindawo zokwakha, kunye nokuzinza kwentsebenzo yayo kunefuthe elibalulekileyo kumgangatho wezakhiwo. I-shrintage yasimahla yeplastiki yindawo enokuthi yenzeke emdaka ngaphambi kokukhuliswa, eziya kubangela iingxaki ezifana nodaka olukhoyo kunye nobudoda. I-seluplose ether, njengesongezelelo esisetyenziswayo elubrqeni, inefuthe elibalulekileyo kwiplastiki yasimahla yokuthoba isidumbu seplastiki.

2. Umgaqo wokucofa i-ether ukunciphisa iplastiki yeplastiki yeplastiki yodaka

I-Selete Ether ineendawo ezigcinwe ngamanzi. Ukuphulukana kwamanzi kumdaka yinto ebalulekileyo ekhokelela kwiplastiki yasimahla. Amaqela e-hydroxyl kwimolekyuli ye-etelulose e-Itesucules kunye neeathom zeoksijini kwi-Ether Hinds ziya kwenza iimolethi ze-hydrogen ezineemolekyuli zamanzi, zijike amanzi asimahla zinciphisa ilahleko yamanzi. Umzekelo, kwezinye izifundo, kwafunyaniswa ukuba ngokunyuka kwe-selsulose ye-selsulose, ilahleko yelahleko yamanzi kubukhoboka benciphile. NjengeI-methyl hydroxdpropyl sethelise (i-HPMC), xa idosi yi-0.1-0.4 (iqhezu elikhulu), inokunciphisa umgangatho wokulahleka kwamanzi okungcola kwesamente nge-9-29%.

I-SelerUlose Ether iphucula iipropathi ze-riheoological, ubume beNethiwekhi yeNethiwekhi kunye noxinzelelo lwe-OSOIC lwe-OSMOTIC ye-SECTIS SOTE, kwaye impahla yayo yokwenza ifilimu ithintela ukwahluka kwamanzi. Olu ngcelele lweendlela lunciphise ngokudibeneyo noxinzelelo oluveliswe yinguqulelo yokufuma kodaka eludango, malunga nokuthintela iplastiki yasimahla.

I-3. Isiphumo se-sethel sether ye-selselose ether kwiplastiki yeplastiki yeplastiki yeplastiki yodaka

Izifundo zibonise ukuba iplastiki yasimahla yeplastiki yokhula Ukuthatha i-HPMC njengomzekelo, xa idosi yi-0.1-0.4 (iqhezu le-Striccord), iplastiki yeplastiki yeplastiki yesamente inokuncitshiswa ngama-30-50%. Kungenxa yokuba idosi inyuka, ukusebenza kwamanzi kunye nokugcinwa kwayo kunye nezinye iziphumo zokuthintela i-shrinkid kuyaqhubeka ukwanda.

Nangona kunjalo, umthamo we-seluplose i-ether ayinakukhula ngokungenasiphelo. Kwelinye icala, ukusuka kwindawo yezoqoqosho, ukongezwa kakhulu kuya kwandisa indleko; Kwelinye icala, kakhulu i-Ersulose I-Ertuse inokuba nefuthe elibi kwezinye iipropathi zodaka, ezinjengamandla odaka.

I-4. Ukubaluleka kwempembelelo ye-selsulose ether kwiplastiki yasimahla yodaka lodaka

Ngokwembono yesicelo sobunjineli bobuchwephesha, ukongezwa okufanelekileyo kwe-Teluplose TARE kwi-Erser kunciphisa iplastiki yeplastiki, ngaloo ndlela kuncitshiswa kokuvela kwamakhoboka. Oku kubaluleke kakhulu ekuphuculeni umgangatho wezakhiwo, ngakumbi ukuphucula ukuqina kwezakhiwo ezinje ngeendonga.

Kwezinye iiprojekthi ezizodwa ezineemfuno eziphezulu zodaka, ezinjengezakhiwo eziphezulu zokuhlala kunye nezakhiwo ezinkulu zikawonke-wonke, ngokulawula iflethi ye-tartulose kwiplastiki yeplastiki, inokuqinisekiswa ukuba iprojekthi ifezekisa imigangatho ephezulu .

I-5. Amathemba ophando

Nangona kukho iziphumo zophando oluthile kwimpembelelo ye-selsulose ether kwiplastiki yasimahla yodaka, kusekho iinkalo ezininzi ezinokuphoswa kubunzulu. Umzekelo, indlela yempembelelo yeentlobo ezahlukeneyo zeselpulose Talupe kwiplastiki yasimahla yokuntywila xa besenza kunye nezinye izongezelelo.

Ngokuphuhliswa okuqhubekayo kwetekhnoloji yokwakha, iimfuno zodaka ngokudakabala zihlala zisanda. Olunye lophando luyafuneka ngendlela yokuphucula ngokuchanekileyo ukusetyenziswa kwe-selsulose e-itelulose emthonjeni ukuze kufezekiswe ezinye iipropathi zodaka.
