Kwishishini lokwakha lanamhlanje, imfuno yezinto ezisebenza kakuhle, ezihlala ixesha elide, nezisebenziseka lula iyaqhubeka nokukhula. Phakathi kwezongezo ezininzi ezisebenzayo ezisetyenziswa kwizixhobo zokwakha ezixutywe nomxube owomileyo,I-Methyl Hydroxyethyl Cellulose (MHEC)iye yavela njengenxalenye ebalulekileyo kwi-grout yethayile kunye ne-putty powder formulations. Njenge-non-ionic cellulose ether, i-MHEC inika iipropati ezibalulekileyo ezifana nokugcinwa kwamanzi, ukuqina, ukuphucula ukusebenza, kunye nokunamathela okuphuculweyo. Abavelisi abaphambili bafanaI-KIMA CHEMICAL CO., LTD, I-Ashland Global Holdings Inc.kunyeIShin-Etsu Chemical Co., Ltd.siyaqhubeka nokuvelisa izinto ezintsha kweli candelo, sibonelela ngeemveliso zeMHEC ezikumgangatho ophezulu ukuhlangabezana neemfuno zokwakha ezitshintshayo.
Imfuno Ekhulayo Yezongezo Zokwakha Ezisebenza Kakhulu
Icandelo lokwakha lehlabathi liphela litshintsha ngokukhawuleza, liqhutywa kukukhula kwezixeko, uphuhliso lweziseko zophuhliso, kunye neenjongo zokuzinza. I-grout yethayile kunye ne-putty powder, njengezinto ezibalulekileyo zokugqiba, kufuneka zihlangabezane neemfuno ezingqongqo ngakumbi ngokubhekiselele ekusebenzeni, ukulula kokusetyenziswa, kunye nokuthobela okusingqongileyo.
Iifomyula zemveli zihlala zijongene nemiba efana nokugcinwa kwamanzi kakubi, ukuqhekeka, ukunamathela okuncinci, kunye nokusebenza okungaguquguqukiyo. Ukungeniswa kwee-ethers ze-cellulose—ingakumbi i-MHEC—kuye kwaphucula kakhulu ezi mpawu, nto leyo eyenza ukuba zibe yimfuneko kwiifomyula zanamhlanje.
Ukuqonda i-MHEC: Ulwakhiwo kunye neNkqubo yokuSebenza
I-Methyl Hydroxyethyl Cellulose (MHEC)yi-non-ionic cellulose ether ephuma kwi-cellulose yendalo ngokuguqulwa kweekhemikhali. Ulwakhiwo lwayo lweemolekyuli lwenziwa ngokwazisai-methoxy (-OCH₃)kwayei-hydroxyethyl (-OCH₂CH₂OH)amaqela kwi-cellulose backbone. Olu tshintsho luphindwe kabini lunika i-MHEC ibhalansi eyahlukileyo yeempawu ze-hydrophilic kunye ne-associative, ezibalulekileyo ekusebenzeni kwayo kwizixhobo zokwakha ezifana ne-tile grout kunye ne-putty powder.
Kwinqanaba le-molecular, umqolo we-cellulose uqulathe iiyunithi zeglucose eziphindaphindayo ezidityaniswe ziibhondi ze-β-1,4-glycosidic. Ukungeniswa kwamaqela e-ether kuphazamisa ukubophelelana okunamandla kwe-hydrogen phakathi kweetsheyini ze-cellulose, okwenza i-polymer inyibilike emanzini. Xa i-MHEC yongezwa emanzini, ifumisa ngokukhawuleza kwaye yenze isisombululo esiqinileyo nesizinzileyo. Iitsheyini ze-polymer ezinde ziyanda kwaye zibambe, zenze inethiwekhi enemilinganiselo emithathu echaphazela kakhulu i-rheology yenkqubo.
Indlela yokusebenza ye-MHEC kwizixhobo ezisekwe kwisamente isekelwe kakhulu kwiukugcinwa kwamanzi, ukuqina, kunye nomsebenzi womphezulu. Yakuba inyibilikisiwe, i-MHEC ifunxa phezu komphezulu wesamente kunye namasuntswana okuzalisa, yenze umaleko wokuthambisa ophucula ukusasazeka kwaye uthintele ukuhlangana. Oku kuphucula ukufana komxube kwaye kunegalelo ekusebenzeni ngcono.
Kwangaxeshanye, i-MHEC ibamba amanzi ngaphakathi kwenethiwekhi yayo ye-polymer, inciphisa isantya somphunga kunye nokufunxwa. Oku kuqinisekisa ukufumaneka kwamanzi ixesha elide ukuze kubekho ukufuma kwesamente, nto leyo ebalulekileyo ekuphuhliseni amandla kunye nokuqina. Ukwanda kwe-viscosity kukwanceda ukumisa amasuntswana aqinileyo, ukuthintela ukubola kwesamente kunye nokuphucula uzinzo.
Enye indlela ebalulekileyo yileukuguqulwa kwe-rheologyI-MHEC inika indlela yokwenza umxube ube mncinci—oko kuthetha ukuba uba mncinci xa ucheba (ngexesha lokuxuba okanye lokufaka) kwaye ubuyisela ubungqindilili xa uphumle. Le propati ivumela ukusetyenziswa okulula ngelixa igcina ukusebenza okuhle kakhulu kokungawi kwiindawo ezithe nkqo.
Ukongeza, i-MHEC inegalelo ekwakhiweni kwefilimu kunye nokudibana kwezinto. Njengoko amanzi ephuma, i-polymer yenza ifilimu eqhubekayo eyomeleza amandla okubopha kwaye inciphise ukuqhekeka. Oku kubaluleke kakhulu kwi-putty powder, apho kufuneka ukugqitywa komphezulu okugudileyo nokuhlala ixesha elide.
Abavelisi abaphambili abafanaI-KIMA CHEMICAL CO., LTDkwayeIShin-Etsu Chemical Co., Ltd.phucula rhoqo amanqanaba okutshintshwa kunye nobunzima bemolekyuli ukuze kulungiselelwe ukusebenza kwe-MHEC kwizicelo ezithile.
