Ungawugweba njani umgangatho weselulosi ngokulula nangokucacileyo?

Iselulosiyinxalenye esisiseko yezityalo, esebenza njengesixhobo solwakhiwo kunye nokubonelela ngokuqina. Ikwasisixhobo esibalulekileyo kumashishini ahlukeneyo, kubandakanya ukwenza amaphepha, amalaphu, kunye nemveliso ye-biofuel. Ukuvavanya umgangatho we-cellulose kubalulekile ekuqinisekiseni ukusebenza kakuhle kunye nokusebenza kakuhle kwezicelo zayo. Ngelixa uvandlakanyo lunokubonakala luntsonkothile, kukho iindlela ezilula nezicacileyo zokugweba umgangatho weselulosi ngempumelelo.

Ubunyulu:

I-cellulose ecocekileyo iqulethe ukungcola okuncinci njenge-lignin, i-hemicellulose, kunye ne-extractives. Ucoceko oluphezulu lubalulekile kumashishini afana namayeza kunye nokutya, apho ukungcola kunokuchaphazela ukhuseleko kunye nomgangatho wemveliso.
Ukuvavanya ubunyulu ngokubonakalayo, jonga umbala weselulosi kunye nokucaca. I-cellulose ecocekileyo ibonakala imhlophe kwaye iguquguquka, ngelixa ukungcola kunokunika umbala kunye nobumnyama.

IMfezeko yoLwakhiwo:

Ubume besakhiwo seselulosi bumisela amandla ayo, ukuguquguquka, kunye nokuqhubekeka. I-cellulose ekumgangatho ophezulu ibonisa ukufana kobude befiber kunye nobubanzi, ebonisa iimpawu ezihambelanayo zesakhiwo.
Yenza uvavanyo olulula lwamandla e-tensile ngokutsala isampulu encinci yeefiber ze-cellulose. I-cellulose esemgangathweni kufuneka ixhathise ukuphuka kunye nokwelula, ibonisa amandla ayo kunye nokuqina.

Isiqulatho sokufuma:

Umxholo wobumanzi uchaphazela iipropati ze-cellulose ezifana nokuzinza kunye nokuqina. Ukufuma okugqithisileyo kunokukhokelela ekukhuleni kwe-microbial kunye nokuthotywa.
Yenza uvavanyo olukhawulezayo lokufuma ngokulinganisa isampulu yeselulosi phambi nasemva kokoma. Ukuncipha kobunzima kubonisa umthamo wokufuma, kunye nokufuma okuphantsi okubonisa umgangatho ophezulu.

Ukuqulunqwa kwemichiza:

Ukuqulunqwa kwe-cellulose kuchaphazela ukunyibilika kwayo, ukusebenza kwakhona, kunye nokufaneleka kwezicelo ezithile. Ukuhlalutya amacandelo ekhemikhali njenge-cellulose, i-hemicellulose, kunye ne-lignin inika ingqiqo kumgangatho we-cellulose.
Sebenzisa iimvavanyo ezilula zeekhemikhali ezifana nokungcoliswa kwe-iodine ukuvavanya ukucoceka kweselulosi. Amabala e-cellulose acocekileyo aluhlaza-mnyama kunye ne-iodine, ngelixa ukungcola kunokubonisa imibala eyahlukileyo okanye akukho ukuphendula.

Iimpawu zokuSebenza:

Ukusebenza kwe-cellulose kwizicelo ezahlukeneyo kuxhomekeke kwizinto ezifana ne-viscosity, i-rheology, kunye ne-absorbency.
Ukuqhuba iimvavanyo zokusebenza ezisisiseko ezifanelekileyo kwisicelo esicetywayo. Umzekelo, ukulinganisa i-viscosity yeselulosi eyenzelwe ukutyeba okanye i-absorbency yeselulosi esetyenziswa kwiimveliso zococeko.
Iindlela ezilula nezicacileyo zoVavanyo:
Ngoku njengoko siyiqonda imiba ephambili yomgangatho weselulosi, makhe sijonge iindlela ezilula zokuvavanya:

UHlolo oluBonakalayo:

Jonga imbonakalo yeesampulu zeselulosi. I-cellulose ecocekileyo kufuneka ibonakale icocekile, imhlophe, kwaye ifana nokuthungwa. Ubukho bombala, amachaphaza, okanye izitenxo zinokubonisa ukungcola okanye ukuthotywa.

Uvavanyo loMzimba:

Yenza iimvavanyo zokujonga izandla njengokukrazula, ukolula, okanye ukusonga iisampulu zeselulosi. I-cellulose ekumgangatho ophezulu kufuneka ibonise amandla, ukuguquguquka, kunye nokomelela ngokuchasene noxinzelelo lomzimba.

Uvavanyo lwamanzi:

Gxininisa isampulu yeselulosi emanzini kwaye ujonge ukuziphatha kwayo. Iselulosi ecocekileyo kufuneka ifunxe amanzi ngokuthe ngcembe ngaphandle kokuqhekeka okanye ukudumba okubonakalayo. Ukudumba okugqithisileyo okanye ukuqhekeka kubonisa umgangatho ophantsi okanye ukungcola okuphezulu.

Uvavanyo lokutshisa:

Ukulayita isampulu encinci yeselulosi ukuvavanya ukutsha kwayo kunye nentsalela. I-cellulose ecocekileyo itshisa ngokucocekileyo kunye nentsalela yothuthu oluncinci, ngelixa ukungcola okufana ne-lignin kunokuvelisa umsi, ivumba, kunye nentsalela eninzi.

Ukugweba umgangatho we-cellulose akufuneki kube nzima. Ngokuqwalasela izinto ezinjengobunyulu, ukuthembeka kwesakhiwo, umxholo wokufuma, ukwakheka kweekhemikhali, kunye neempawu zokusebenza, kunye nokusebenzisa iindlela ezilula zokuvavanya, umntu unokuvavanya ngokunyanisekileyo umgangatho weselulosi. Nokuba ukwishishini lokwenza iphepha, ukuvelisa amalaphu, okanye uphonononga ukhetho lwe-biofuel, ukuqonda umgangatho weselulosi kubalulekile ukuze ufumane iziphumo ezizezona zilungileyo kwizicelo zakho.
