IHydroxypropyl Methylcellulose (HPMC)sisongezelelo sezinto zokwakha ezibalulekileyo kwaye isetyenziswa kakhulu kwi-putty, i-adhesive tile, i-waveld wall, kunye nezinye iindawo. Ukusebenza kwayo okuphezulu kuye kwaphucula kakhulu iglue yokwakha i-putty. Eli nqaku liza kuhlalutya ulwahlulo lwe-putty yokwakha iglue esekwe kumsebenzi we-HPMC cellulose kwaye iphonononge imfuno yayo yentengiso kunye nophuhliso.
(1) Inkcazo yeglue yokwakha i-putty
Iglu yesakhiwo sePutty sisincamathelisi sesakhiwo esisetyenziselwaukulungisa nokugcwalisa umphezulu wokwakhaezifana neendonga, iisilingi, kunye nemigangatho. Umsebenzi wayo ophambili kukuphucula ukunamathela, ukumanzi, kunye nokusebenza kokwakhiwa kweputty. Ukuze kuphuculwe isiphumo sokwakha kunye nomgangatho wokugqibela wokuqina we-putty, ezininzi iiglue zokwakha ze-putty ziya kongeza ezinye izinto ezilungisiweyo, ezifana ne-Hydroxypropyl Methylcellulose (HPMC).
I-HPMC idlala indima ephambili elandelayo kwi-putty:
- Ukuphucula ubumanzi:I-HPMC inokuphucula ngokufanelekileyo ukumanzi kwe-putty slurry, ukwenza ulwakhiwo lube lula kwaye lusebenze lula.
- Ukuphucula ukunamathela:I-HPMC inokwandisa amandla okudibanisa phakathi kwe-putty kunye nodonga okanye umaleko wesiseko, ukunciphisa ukuchithwa kunye nokuqhekeka.
- Yandisa ixesha lokuvula:Emva kokongeza i-HPMC, ixesha lokusebenza kwe-putty linokwandiswa, elilungele ukulungelelanisa isimo sokwakha kunye nokunciphisa inkunkuma yezinto eziphathekayo.
- Thintela ukuhluma kunye nemvula:I-HPMC nayo inokugcinwa kwamanzi athile, okunqanda ukucwangciswa kunye nemvula ye-putty ngexesha lokugcinwa kunye nokusetyenziswa.

(2) Ukuhlelwa kweglue yokwakha kwi-putty
Ukuhlelwa kweglue yokwakha ye-putty inokwahlulwa ngokubunjwa kwayo, umsebenzi, imeko yesicelo, kunye nezinye izinto. Ngokuqhelekileyo, i-putty glue inokwahlulwa ngokwezi ndidi zilandelayo:
1. Ukuhlelwa ngokwendlela yokubhala
Iglue esekelwe emanzini
Iglue esekelwe emanzini iyona ndlela iqhelekileyo ye-putty glue. Izinto zayo ezisisiseko ziyi-resin e-soluble yamanzi kunye nezinye izongezo zekhemikhali ezinyibilikayo emanzini. Iglue esekelwe emanzini ineenzuzo zeukhuseleko lokusingqongileyo, non-toxicity, kwaye akukho ivumba. Ihlangabezana neemfuno zezakhiwo eziluhlaza kwaye ifanelekile ukuhlobisa ikhaya, izakhiwo zoluntu kunye nezinye iindawo. I-HPMC, njengenxalenye ebalulekileyo yeglue esekelwe emanzini, inokuphucula ngokufanelekileyo amandla ayo okudibanisa kunye nokusebenza kokwakha.
Iglu esekelwe kwi-solvent
Iglu esekwe kwi-solvent isebenzisa isinyibilikisi njengendlela yokusasaza. Ine-aamandla okudibanisa aphezulukwaye idla ngokufanelekela iindawo ezithile zokwakha ezikhethekileyo, njengeendawo zokufuma okuphezulu. Nangona iglu esekelwe kwisinyibilikisi isetyenziswa kakhulu, ukusetyenziswa kwayo kwizakhiwo zale mihla kuthintelwe ngenxa yokuba izinyibilikisi zayo eziguquguqukayo zinokungcolisa imekobume.
2. Ukuhlelwa ngokomsebenzi
I-putty glue eqhelekileyo
I-putty glue eqhelekileyo ifanelekile ukulungiswa kweendonga kwizindlu eziqhelekileyo kunye nezakhiwo zorhwebo. Umsebenzi wayo oyintloko kukunyusa ukubambelela phakathi kwe-putty kunye nesiseko sesiseko kunye nokuphucula ukusebenza kokwakhiwa. Ixabiso lale glu lihlala liphantsi kwaye lifanelekile kwizicelo ezinkulu.
Iglu engangenwa ngamanzi
I-putty glue engangeni manzi yenzelwe ukumelana neendawo ezifumileyo okanye iiprojekthi zokwakha ezidibana ngokuthe ngqo namanzi, njengamagumbi okuhlambela, amakhitshi kunye nezinye iindawo. Ayinayo nje ukusebenza kwe-putty glue eqhelekileyo, kodwa ikhusela ngempumelelo umswakama ukuba ungangeni eludongeni. I-putty glue engangeni manzi ihlala yongeza izongezo ezikhethekileyo ezingangeni manzi, ezinje ngeemulsion ezingangeni manzi kunye nemathiriyeli esekwe kwisamente.
Anti-crack putty iglu
I-Anti-crack putty glue ijolise kwingxaki yokuqhekeka enokuthi yenzeke eludongeni ngexesha lokusetyenziswa, kwaye iphucula ukuxhathisa ukuqhekeka ngokusebenzisa ii-resin eziguquliweyo okanye izixhasi ze-elastic. Olu hlobo lweglue putty ludla ngokusetyenziswa kwizakhiwo ezichatshazelwa lula lutshintsho lobushushu okanye ukungcangcazela kwesakhiwo, njengeendonga zangaphandle, uphahla kunye nezinye iindawo.

3. Ukuhlelwa ngokwendlela yokwakha
Iglue yokwakha ngesandla
Le glu ifanelekile kwiindlela zokwakha zendabuko, kwaye kufuneka igqitywe nge-brush manual, i-smearing, njl. Umsebenzi wayo oyintloko yindleko ephantsi kwaye ifanelekile ukulungiswa kwezinto ezincinci okanye ukuhlobisa.
Iglu yomatshini wokutshiza
Iglue yomatshini wokutshiza isetyenziswa ikakhulu kwiiprojekthi zolwakhiwo olukhulu, ngakumbi izakhiwo eziphakamileyo ezifuna isixa esikhulu se-putty. Ukusebenzisa izixhobo zokutshiza ukwakhiwa akukwazi nje ukuphucula ukusebenza kakuhle kokwakhiwa, kodwa nokuqinisekisa ukuhanjiswa okufanayo kweglue kunye nokunciphisa inkunkuma.
4. Ukuhlelwa ngokwezongezo
I-putty glue eqhelekileyo
Olu hlobo lweglue lusebenzisa izongezo eziqhelekileyo kwaye lufanelekile ukwakhiwa kweendonga ngokubanzi. HPMC idlala indima ebalulekileyo kuyo, ukuphucula fluidity kunye nokusebenza.
I-putty glue elungisiweyo
I-modified putty glue iya kongeza izongezo zekhemikhali ezikhethekileyo, ezifana ne-polymer emulsions, elastomers, njl.ukunamathela, ukuqina kunye nokumelana nemozuluyeglue, kwaye ifaneleke ngokukodwa kwiiprojekthi zokwakha ezifunwa kakhulu.

(3) Imfuno yemarike kunye nentsingiselo yophuhliso
Ngophuhliso olukhawulezayo lweshishini lokwakha, imfuno yeglue yokwakha i-putty iyanda. Ngokukodwa kwimeko yeemfuno ezingqongqo zokhuseleko lokusingqongileyo,I-putty glue esekelwe emanzini iye ngokuthe ngcembe ibe yeyona nto iphambili kwiimarike. Ukuze kuhlangatyezwane nemfuno yemarike, abaninzi abavelisi beselulosi be-HPMC banyusa iinzame zabo ze-R&D zokukhuthaza ukwenziwa kwezinto ezintsha kobuchwepheshe beglu yokwakha kwiputty. Ngokomzekelo, abaninzi abavelisi baqala ukuphuhlisai-low-VOC (i-volatile organic compounds) okanye i-VOC-free yeglue ehambelana nokusingqongileyoukuhlangabezana neemfuno zezakhiwo eziluhlaza.
Ngokuhambela phambili kwetekhnoloji yokwakha, itekhnoloji yokutshiza ngoomatshini nayo iya iba ngumkhwa. Le ndlela ayiphuculi nje kuphela ukusebenza kakuhle kolwakhiwo, kodwa inciphisa imfuno yabasebenzi, ngoko isetyenziswa ngokubanzi kwizakhiwo eziphakamileyo, izakhiwo zorhwebo, kunye nezinye iindawo.
Ukuhlelwa kweglue yokwakha ye-putty yahlulwe ngokukodwa ngokwemilinganiselo eyahlukeneyo efana nokubunjwa, umsebenzi kunye nendlela yokwakha. Njengesongezo esibalulekileyo,HPMCidlala indima ebalulekileyo ekuphuculeni ukusebenza, ukusebenza kokwakhiwa, kunye nokunamathela kwe-putty glue. Ngokunyuka kwemfuno yezinto zokwakha ezihambelana nokusingqongileyo kunye nokusebenza okuphezulu kwimarike yokwakha, iglue yokwakha ye-putty iya kuqhubeka nokuphucula kwaye iphuhlise ngendlela eluhlaza, ehambelana nokusingqongileyo, kunye nesikhokelo esifanelekileyo. Abavelisi be-cellulose be-HPMC badlala indima ebaluleke kakhulu kule nkqubo, kwaye ukuveliswa kwezinto ezintsha kunye nophuhliso lwetekhnoloji kuya kuchaphazela ngokuthe ngqo kwicala lemarike yonke.
