IHydroxypropylmethylcellulose (HPMC) yipolymer eyenziweyo esetyenziswa kwiintlobo ngeentlobo zamashishini abandakanya amayeza, izinto zokuthambisa kunye nokwakha. Yikhompawundi engeyotyhefu kunye ne-biodegradable eneempawu ezigqwesileyo zokugcina amanzi. Nangona kunjalo, kwezinye izicelo, i-HPMC inokubonisa ugcino lwamanzi kakhulu, nto leyo enokuba yingxaki. Kweli nqaku, sixoxa ngezizathu ezine eziphambili zokuba kutheni i-HPMC igcina amanzi kunye nezisombululo ezinokwenzeka zokunciphisa ingxaki.
1. Ubungakanani besuntswana kunye neqondo lokutshintshwa
Enye yezona zinto zibalulekileyo ezichaphazela ugcino lwamanzi e-HPMC bubungakanani bamasuntswana kunye neqondo lokutshintsha (DS). Kukho amabanga ahlukeneyo e-HPMC, ngalinye line-DS ethile kunye nobungakanani bamasuntswana. Xa sithetha ngokubanzi, iqondo eliphezulu lokutshintshwa kwe-HPMC, kokukhona uphezulu umthamo wogcino lwamanzi. Nangona kunjalo, oku kukhokelela kwi-viscosity ephezulu, echaphazela ukuqhubekeka kwezicelo ezithile.
Ngokunjalo, ubungakanani bamasuntswana bukwachaphazela ukugcinwa kwamanzi kweHPMC. Ubungakanani bamasuntswana amancinane iHPMC iya kuba nommandla ophezulu womphezulu onokubamba amanzi amaninzi, okukhokelela kugcino lwamanzi oluphezulu. Ngakolunye uhlangothi, ubukhulu be-particle ubukhulu be-HPMC buvumela ukusasazwa okungcono kunye nokuxuba, okubangela ukuzinza okungcono ngaphandle kokugcinwa kwamanzi okubalulekileyo.
Isisombululo esinokwenzeka: Ukukhetha ibakala elifanelekileyo le-HPMC kunye neqondo eliphantsi lokutshintshwa kunye nobukhulu beqhekeza elikhulu kunokunciphisa ukugcinwa kwamanzi ngaphandle kokuchaphazela ukusebenza kwesicelo.
2. Iimeko zokusingqongileyo
Iimeko zokusingqongileyo ezifana nobushushu kunye nokufuma kunokuchaphazela kakhulu ukugcinwa kwamanzi kwe-HPMC. I-HPMC inokufunxa kwaye igcine ukufuma kwimeko-bume engqongileyo, nto leyo enokukhokelela kugcino lwamanzi ngokugqithisileyo okanye ukoma okucothayo. Amaqondo obushushu aphezulu akhawulezisa ukufunxa nokugcinwa komswakama, ngelixa amaqondo obushushu aphantsi acothisa inkqubo yokomisa, nto leyo ebangela ukugcinwa komswakama. Ngokunjalo, iindawo zokufuma eziphezulu zinokubangela ugcino lwamanzi olugqithisileyo kunye nokuvuselelwa kwakhona kwe-HPMC.
Isisombululo esinokwenzeka: Ukulawula iimeko zokusingqongileyo apho i-HPMC isetyenziswa khona kunokunciphisa kakhulu ukugcinwa kwamanzi. Umzekelo, ukusebenzisa i-dehumidifier okanye i-air conditioner inokunciphisa ukufuma kwendawo, ngelixa ukusebenzisa i-fan okanye i-heater kunokunyusa ukuhamba komoya kunye nokunciphisa ixesha elithatha i-HPMC ukuba yome.
3. Ukuqhubekeka okuxutyiweyo
Ukuxutywa kunye nokusebenza kwe-HPMC nako kunokuchaphazela iimpawu zayo zokugcina amanzi. Indlela i-HPMC exutywe ngayo kwaye iqhutywe ngayo inokumisela umthamo wayo wokubamba amanzi kunye neqondo lokuhamba kwamanzi. Ukungonelanga ukuxutywa kwe-HPMC kunokubangela ukudityaniswa okanye i-caking, echaphazela umthamo wokubamba amanzi. Ngokufanayo, ukudibanisa ngokugqithiseleyo okanye ukucubungula ngokugqithiseleyo kunokubangela ukunciphisa ubungakanani beqhekeza, okwandisa ukugcinwa kwamanzi.
Izisombululo ezinokwenzeka: Ukuxuba okufanelekileyo kunye nokusebenza kunokunciphisa kakhulu ukugcinwa kwamanzi. I-HPMC kufuneka ixutywe okanye ixutywe ngokucokisekileyo ukuqinisekisa ukuhanjiswa okufanayo kunye nokuthintela ukwakheka kwamaqhuma okanye amaqhuma. Ukuxutywa ngokugqithisileyo kufuneka kuphetshwe kwaye iimeko zokusetyenzwa zilawulwe ngononophelo.
4. Ifomula
Ekugqibeleni, ukuqulunqwa kwe-HPMC kukwachaphazela iipropati zayo zokugcina amanzi. I-HPMC isoloko isetyenziswa ngokudibeneyo nezinye izongezo, kwaye ukuhambelana kwezi zongezo kuya kuchaphazela ukugcinwa kwamanzi kwe-HPMC. Umzekelo, ezinye i-thickeners okanye i-surfactants inokunxibelelana ne-HPMC kwaye yandise umthamo wayo wokubamba amanzi. Ngakolunye uhlangothi, ezinye iityuwa ze-inorganic okanye i-acids zinokunciphisa umthamo wokubamba amanzi ngokuthintela ukubunjwa kweebhondi ze-hydrogen.
Izisombululo ezinokwenzeka: Ukuqulunqwa ngokucophelela kunye nokukhethwa kwezongezo kunokunciphisa kakhulu ukugcinwa kwamanzi. Ukuhambelana phakathi kwe-HPMC kunye nezinye izongezo kufuneka ziqwalaselwe ngononophelo kwaye impembelelo yazo kugcino lwamanzi ivavanywe. Ukukhetha izongezo ezinempembelelo encinci ekugcinweni kwamanzi kunokuba yindlela efanelekileyo yokunciphisa ukugcinwa kwamanzi.
ukuququmbela
Ukuqukumbela, i-HPMC ibe yipolymer eyimfuneko kumashishini ahlukeneyo ngenxa yeempawu zayo ezibalaseleyo zokugcina amanzi. Nangona kunjalo, kwezinye izicelo, ukugcinwa kwamanzi amaninzi kunokuba yingxaki. Ngokuqonda izinto ezichaphazela ukugcinwa kwamanzi kunye nokusebenzisa izisombululo ezifanelekileyo, ukugcinwa kwamanzi kwe-HPMC kunokunciphisa kakhulu ngaphandle kokunciphisa ukusebenza.
