Iimpembelelo zobhubhani we-COVID-19 zinokuvakala kulo lonke ishishini lemichiza.Ukungakwazi okukhulayo kwimveliso kunye neenkqubo zokuvelisa, ekukhanyeni kwabasebenzi abazimeleyo kuye kwabangela ukuphazamiseka okukhulu kwikhonkco lokubonelela kulo lonke icandelo.Izithintelo ezikhuthazwa ngulo bhubhani zithintela ukuveliswa kwezinto eziyimfuneko ezifana namayeza asindisa ubomi.

Ubume bokusebenza kwizityalo zemichiza ezingenakumiswa lula kwaye ziqaliswe, zenza izithintelo zokusebenza kwezi zityalo zibe yinkxalabo enzulu kwiinkokheli zoshishino.Ukuthunyelwa okuthintelweyo kunye nokulibaziseka okuvela eChina kuye kwadala ukunyuka kwexabiso kwizinto eziphathekayo, okuchaphazela undoqo woshishino lweekhemikhali.

Imfuno ethotyiweyo evela kumashishini aneempembelelo ahlukeneyo afana neemoto inefuthe elibi ekukhuleni kweshishini lemichiza.Ngenxa yobunzima obukhoyo, iinkokeli zemarike zigxile ekuzithembeni ekulindeleke ukuba kuxhamle ukukhula koqoqosho lwezoqoqosho olwahlukeneyo kwixesha elide.Iinkampani ziqala imisitho ukuze zihlengahlengise kwaye zibuyise ilahleko eyenzeke ngexesha lobhubhani we-COVID-19.

I-Polyanionic cellulose (PAC) luhlobo lwe-ether e-soluble cellulose derivative eyenziwa yi-chemical modification ye-cellulose yendalo.Luhlobo olubalulekileyo lwe-ether eselulosi enyibilikayo emanzini.I-Polyanionic cellulose ifumana usetyenziso olubalulekileyo kuphononongo kunye nokuveliswa kwe-offshore, ukugrumba kunye nokusebenza kakuhle kwetyuwa kwishishini le-oyile kunye negesi.Ngumgubo omhlophe okanye omthubi, ongenavumba, onehygroscopic, ongenancasa, kwaye awunatyhefu.Iyanyibilika emanzini kuwo omabini amaqondo aphantsi kunye namaqondo aphezulu, kwaye yenza ulwelo olungqindilili xa inyibilikiswa emanzini.

I-PAC ibonisa uzinzo oluphezulu kwizicelo zobushushu obuphezulu kwaye ibonisa ukuxhathisa okuphezulu kwiindawo ezinetyuwa ngokunjalo.Ikwafunyaniswa ukuba ineempawu ezichasayo.I-Polyanionic cellulose slurry ibonisa ilahleko ephezulu yokunciphisa ulwelo, amandla okulahlwa kunye nokunyamezela ubushushu obuphezulu kwizicelo ezahlukeneyo.Ngaphaya koko, i-polyanionic cellulose ifumana usetyenziso kuluhlu olwahlukeneyo lwamashishini kuluhlu olubanzi losetyenziso ngaphandle kweshishini leoli kunye negesi.Umzekelo, ukutya kunye nesiselo, amayeza, iikhemikhali, iplastiki kunye nepolymer zezinye zemizi-mveliso yokusetyenziswa kokugqibela ekufuneka iqatshelwe.

Ukuthathela ingqalelo le miba ibalulekileyo yokusetyenziswa kwe-polyanionic cellulose, uphononongo lwentengiso ye-polyanionic cellulose iba yinto ebalulekileyo yokufunda.

Kukhangelo lwee-hydrocarbons zokuqinisekisa unikezelo olugudileyo, lwexesha elide lweoyile ekrwada kunye negesi yendalo kunye nokwanela kwamandla, ukuphononongwa kwepetroleum kunye neenkampani zemveliso ziye zaqulunqa amaqhinga okufumana nokuphuhlisa i-oyile engaselunxwemeni kunye nerhasi kumanzi anzulu, kunye neemeko ezirhabaxa ezinxwemeni. .Oku kuguqulela ekunyukeni kwemfuno ye-polyanionic cellulose, njengoko inezicelo ezibalulekileyo kumxholo wokuguqula iipropathi zolwelo lokomba ukuze kuqinisekiswe ukusebenza kwenkonzo ye-oyile egudileyo.I-Polyanionic cellulose ibonelela ngolawulo oluphezulu lokuhluza kunye ne-viscosity eyongezelelweyo kumanzi amaninzi asekelwe emanzini, i-vis-à-vis nezinye iikhemikhali ze-oilfield.Oku kube yinto ebalulekileyo eqhuba ukukhula kwemarike ye-polyanionic cellulose.

Kutshanje, kuye kwakho ukonyuka kwemfuno ye-polyanionic cellulose evela kumzi-mveliso okhula ngokukhawuleza wokutya kunye nesiselo.Oku kunjalo ngenxa yokuba i-cellulose ye-polyanionic ibonakalise ukuba ikhuselekile ngakumbi kwi-vis-à-vis ezinye iikhemikhali, njengesongezo sokutya, ngaloo ndlela ifumana ukusetyenziswa okukhethekileyo.I-Polyanionic cellulose ikwafumana ukusetyenziswa okwandisiweyo kwiinkqubo zokucoca amanzi kushishino lokutya kunye nesiselo.Ikwasetyenziswa ngokubanzi njengesizinzisi kunye nesityebi kwimveliso yokutya.Umzekelo, iimveliso zejeli kunye ne-ayisikhrimu zizinzisiwe kwaye zityebe kakhulu ngokusetyenziswa kwe-polyanionic cellulose (PAC).I-PAC ikwaluncedo ngenxa yokuhambelana kwayo ukuba ifakwe enkonkxeni kwaye igcinwe ixesha elide, ngaloo ndlela ibe lukhetho oludumileyo njengesizinzisi sokutya.Ikwasetyenziswa kakhulu ukuzinzisa iigravies kunye neziqhamo kunye nemifuno yejusi.Ukukhula okukhawulezayo kweshishini lokutya kunye neziselo kukwanegalelo ekukhuleni kwentengiso ye-polyanionic cellulose kwinqanaba lehlabathi.Kumashishini amayeza, i-polyanionic cellulose ifumana ukubaluleka njenge-emulsifier & stabilizer ekwenzeni amayeza kunye neepilisi ezitofwayo ngenxa yeempawu zayo ezisebenzayo.
