IHydroxypropyl Methylcellulose (HPMC)iyisengezo sezinto zokwakha ezibalulekile futhi isetshenziswa kakhulu ku-putty, i-adhesive tile, enamathela odongeni, neminye imikhakha. Ukusebenza kwayo okuphezulu kuye kwathuthukisa kakhulu i-putty building glue. Le ndatshana izohlaziya ukuhlukaniswa kweglue yokwakha i-putty ngokusekelwe emsebenzini we-HPMC cellulose futhi ihlole isidingo sayo semakethe nokuthuthuka.
(1) Incazelo yeglue yokwakha i-putty
I-Putty building glue iyingcina yesakhiwo esetshenziselwaukulungisa nokugcwalisa izindawo zokwakhanjengezindonga, usilingi, naphansi. Umsebenzi wayo oyinhloko ukuthuthukisa ukunamathela, uketshezi, nokusebenza kokwakhiwa kwe-putty. Ukuze kuthuthukiswe umphumela wokwakha kanye nekhwalithi yokugcina eqinile ye-putty, amaglue amaningi okwakha ama-putty azokwengeza izinto eziguquliwe, njengeHydroxypropyl Methylcellulose (HPMC).
I-HPMC idlala izindima ezibalulekile ezilandelayo ku-putty:
- Ukuthuthukisa i-fluidity:I-HPMC ingathuthukisa ngempumelelo i-fluidity ye-putty slurry, yenze ukwakhiwa kube bushelelezi futhi kube lula ukusebenza.
- Ukuthuthukisa ukunamathela:I-HPMC ingathuthukisa amandla okubopha phakathi kwe-putty nodonga noma isendlalelo sesisekelo, inciphise ukuchithwa nokuqhekeka.
- Nweba isikhathi sokuvula:Ngemva kokwengeza i-HPMC, isikhathi sokusebenza se-putty singanwetshwa, esivumelana nokulungisa isimo sokwakha nokunciphisa udoti wezinto ezibonakalayo.
- Vimbela i-stratification nemvula:I-HPMC futhi inokugcinwa kwamanzi okuthile, okugwema ukumiswa kanye nemvula ye-putty ngesikhathi sokugcina nokusebenzisa.

(2) Ukuhlukaniswa kweglue yokwakha ye-putty
Ukuhlukaniswa kweglue yokwakha ye-putty kungahlukaniswa ngokusho kokwakheka kwayo, umsebenzi, isimo sohlelo, nezinye izici. Ngokuvamile, i-putty glue ingahlukaniswa ngezigaba ezilandelayo:
1. Ukuhlukaniswa ngokwakhiwa
Iglue esekelwe emanzini
I-glue esekelwe emanzini iwuhlobo oluvame kakhulu lwe-putty glue. Isisekelo sayo siyi-resin encibilika emanzini nezinye izithasiselo zamakhemikhali ezincibilika emanzini. I-glue esekelwe emanzini inezinzuzo zeukuvikelwa kwemvelo, ukungabi nobuthi, futhi akukho phunga. Ihlangabezana nezidingo zezakhiwo eziluhlaza futhi ifanele ukuhlobisa ikhaya, izakhiwo zomphakathi, nezinye izindawo. I-HPMC, njengengxenye ebalulekile yeglue esekwe emanzini, ingathuthukisa ngempumelelo amandla ayo okubopha kanye nokusebenza kokwakha.
Iglue esekelwe ku-solvent
I-solvent-based glue isebenzisa i-solvent njengendlela yokuhlakazeka. Ine-aamandla okubopha okuphezulufuthi ngokuvamile ifanelekela izindawo ezithile zokwakha ezikhethekile, njengezindawo ezinomswakama ophezulu. Nakuba iglue esekelwe kuncibilikisi isetshenziswa kabanzi, ukusetshenziswa kwayo ezakhiweni zesimanje kulinganiselwe ngoba izincibilikisi zayo eziguquguqukayo zingase zingcolise indawo ezungezile.
2. Ukuhlukaniswa ngomsebenzi
I-putty glue evamile
I-putty glue evamile ifaneleka ukulungiswa kodonga ezindlini ezijwayelekile kanye nezakhiwo zezohwebo. Umsebenzi wayo oyinhloko ukukhulisa ukunamathela phakathi kwe-putty kanye nesendlalelo sesisekelo nokuthuthukisa ukusebenza kokwakhiwa. Intengo yale ngcina ngokuvamile iphansi futhi ifanele ukusetshenziswa kwenani elikhulu.
I-putty glue engangeni manzi
I-putty glue engangeni manzi iklanyelwe ukubhekana nezindawo ezinomswakama noma amaphrojekthi wokwakha athintana ngqo namanzi, njengezindlu zangasese, amakhishi nezinye izindawo. Ayinayo nje ukusebenza kwe-putty glue evamile, kodwa futhi ivimbela ngokuphumelelayo umswakama ukuthi ungangeni odongeni. I-putty glue engangeni manzi ngokuvamile yengeza izithasiselo ezikhethekile ezingangeni manzi, njengama-emulsion angangeni manzi nezinto ezenziwe usimende.
I-anti-crack putty glue
I-Anti-crack putty glue ihlose inkinga yokuqhekeka engase yenzeke odongeni ngesikhathi sokusetshenziswa, futhi ithuthukisa ukumelana kwayo nokuqhekeka ngokusebenzisa ama-resin aguquliwe noma izithuthukisi ezinwebekayo. Lolu hlobo lwe-putty glue luvame ukusetshenziswa ezakhiweni ezithinteka kalula ngokushintsha kwezinga lokushisa noma ukudlidliza kwesakhiwo, njengezindonga zangaphandle, uphahla, nezinye izingxenye.

3. Ukuhlukaniswa ngendlela yokwakha
Iglue yokwakhiwa kwezandla
Le glue ifaneleka ezindleleni zendabuko zokwakha manual, futhi idinga ukugcwaliswa ngokuxubha ngesandla, ukugcoba, njll. Isici sayo esiyinhloko siyizindleko eziphansi futhi zifanele ukulungiswa okuncane noma ukuhlobisa.
Mechanical spray glue
I-Mechanical spray glue isetshenziswa ikakhulukazi kumaphrojekthi wokwakha amakhulu, ikakhulukazi izakhiwo eziphakeme ezidinga inani elikhulu le-putty coating. Ukusebenzisa imishini yokufutha ekwakheni akukwazi nje ukuthuthukisa ukusebenza kahle kokwakhiwa, kodwa futhi kuqinisekise ukusatshalaliswa okufanayo kweglue nokunciphisa imfucuza.
4. Ukuhlukaniswa ngezithasiselo
I-putty glue evamile
Lolu hlobo lweglue lusebenzisa izithasiselo ezivamile futhi lufanele ukwakhiwa kodonga olujwayelekile. I-HPMC idlala indima ebalulekile kuyo, ithuthukisa uketshezi nokusebenza kwayo.
I-putty glue eshintshiwe
I-modified putty glue izokwengeza izithasiselo zamakhemikhali ezikhethekile, njenge-polymer emulsion, ama-elastomers, njll. Lezi zithako zingathuthukisa ukuukunamathela, ukunwebeka kanye nokumelana nesimo sezuluyeglue, futhi ifaneleka ngokukhethekile kumaphrojekthi wokwakha adingeka kakhulu.

(3) Ukufunwa kwezimakethe kanye nentuthuko
Ngokuthuthuka okusheshayo kwemboni yezokwakha, isidingo seglue yokwakha ye-putty siyanda. Ikakhulukazi esimweni sezimfuneko eziqinile zokuvikelwa kwemvelo,I-putty glue esekelwe emanzini kancane kancane ibe yinto evamile emakethe. Ukuze kuhlangatshezwane nesidingo semakethe, abakhiqizi abaningi be-HPMC cellulose bakhulisa imizamo yabo ye-R&D yokukhuthaza ukuqanjwa kabusha kwezobuchwepheshe kweglue yokwakha ye-putty. Isibonelo, abakhiqizi abaningi bayaqala ukuthuthukisai-low-VOC (izinto eziphilayo eziguquguqukayo) noma amaglue angenawo i-VOC ahambisana nemveloukuhlangabezana nezidingo zezakhiwo eziluhlaza.
Ngokuthuthuka kobuchwepheshe bokwakha, ubuchwepheshe bokufafaza ngemishini bubuye buphenduke umkhuba. Le ndlela ayigcini nje ukuthuthukisa ukusebenza kahle kokwakhiwa, kodwa futhi inciphisa isidingo sabasebenzi, ngakho-ke isetshenziswa kabanzi ezakhiweni eziphakeme, ezakhiweni zezentengiselwano, nakweminye imikhakha.
Ukuhlukaniswa kweglue yokwakha ye-putty kuhlukaniswe ngokuyinhloko ngobukhulu obuhlukahlukene njengokubunjwa, umsebenzi, nendlela yokwakha. Njengesengezo esibalulekile,I-HPMCidlala indima ebalulekile ekuthuthukiseni ukusebenza, ukusebenza kokwakhiwa, nokunamathela kwe-putty glue. Ngokukhula kwesidingo sezinto zokwakha ezinobungani bemvelo nezisebenza kahle kakhulu emakethe yokwakha, iglue yokwakha ye-putty izoqhubeka nokuthuthuka futhi ithuthuke ngendlela eluhlaza, evumelana nemvelo, futhi esebenza kahle. Abakhiqizi be-cellulose be-HPMC badlala indima ebalulekile kule nqubo, futhi ukusungulwa komkhiqizo wabo kanye nokuthuthukiswa kobuchwepheshe kuzothinta ngqo isiqondiso sayo yonke imakethe.
