Ukugcinwa kwamanzi amaninzi kwe-MHEC kufanelekile ngokukodwa kwiindawo ezifunxa amanzi kakhulu, imozulu eyomileyo, kunye nokwakhiwa kwehlobo.
1.2. Uphuculo Lokusetyenziswa Nokusebenza Kokukrazula
I-MHEC inezakhono ezibalaseleyo zokulawula i-rheological, nto leyo enika i-tile adhesive ezi mpawu zilandelayo:
Ukusetyenziswa okuthambileyo;
Ulawulo lobukhulu obufanayo;
Iimpawu zokungabophi imitya kunye nokunganamatheli.
Kubasebenzi, kulula ukwenza ii-serration ezifanayo, nto leyo ephucula ukusebenza kakuhle.
1.3. Iimpawu Ezintle Zokuthintela Ukutyibilika
I-MHEC ilawula ngokufanelekileyo i-thixotropy ye-adhesive yethayile, inyusa ukunyibilika kwayo phantsi kwamandla okucheba kwaye ibuyisela ngokukhawuleza ukuhambelana kwayo emva kokusetyenziswa. Olu phawu luphucula ngokuthe ngqo i-tack yokuqala yethayile, ngaloo ndlela:
Ukuthintela ukugoba kwethayile;
Ukuphucula uzinzo lokubeka ngokuthe nkqo;
Ukunciphisa ukuphinda usebenze.
Indlela esiya kwiithayile ezinkulu nezinzima ngayo yenza ukuba inzuzo ye-MHEC engatyibilikiyo ibe yeyona ibalulekileyo.
1.4. Ixesha Elivulekileyo Elide kunye Nokunyamezelana Okuphuculweyo
I-MHEC, ngokugcinwa kwamanzi kunye nolawulo lwe-rheological, inciphisa izinga lokulahleka kwamanzi kumphezulu we-adhesive yethayile, ivumela abafaki ixesha elingakumbi lokusebenza kwethayile, ngakumbi ezifanelekileyo kwiindawo ezinkulu, ukuphucula ukusebenza kakuhle kokwakha kunye nomgangatho wemveliso egqityiweyo.
2. Iingenelo ze-MHEC kwiPutty Powder
2.1. Ukugcinwa Kwamanzi Okuphuculweyo, Ukuqinisekisa Ukwenziwa Kwefilimu Efanayo Ye-Putty
Iileya ze-putty ezincinci zinokuba neengxaki ezifana nokushwabana, ukuqhekeka, kunye nokugutywa ukuba amanzi akagcinwanga kakuhle. Umthamo ophezulu wokugcinwa kwamanzi kwi-MHEC unokwenza oku kulandelayo:
Ukuthintela ukulahleka kwamanzi kwangethuba kwi-putty;
Qinisekisa ukuba yomiswa kwaye ivuthwa ngokulinganayo;
Kuphephe ukubila, ukuguba, kunye nokuqhekeka.
Ukubaluleka kwe-MHEC kubonakala ngakumbi xa kufakwa i-putty yangaphandle eludongeni okanye kwiindawo ezinobushushu obuphezulu.
2.2. Ukuphuculwa Kokusebenza Nokugudama Kokusetyenziswa
I-MHEC iphucula kakhulu ukutyeba kwe-putty, okwenza ukusetyenziswa kwayo kube lula:
Ukusetyenziswa okulula nokungacinezeliyo;
Umphezulu othambileyo nococekileyo;
Akulula ukukrwela kunye nokuqokelelana kweentsalela.
Oku kunceda ngokuthe ngqo ekuphuculeni ukuguda kodonga kunye nokunamathelana ngcono kweepeyinti ezilandelayo.
2.3. Iimpawu eziphuculweyo ze-Rheological ze-Putty
Ngokusebenzisa ukuqina kunye nokulungiswa kwe-thixotropic kwinkqubo, i-MHEC inika umgubo we-putty ezi mpawu zilandelayo:
Ukuqina okuphezulu xa uphumle, okuthintela ukugoba;
Ukukwazi ukuhamba kakuhle xa ucheba, okwenza kube lula ukuyifaka;
Ukuzivumelanisa nezimo ngamandla nesantya sokusetyenziswa kunye neendlela ezahlukeneyo.
Ngoko ke, bobabini abaqalayo kunye nabasebenzi abanamava banokufikelela kumava angcono okufaka isicelo.
2.4. Ukunamathela Okuphuculweyo kunye Nokuqina Kokuzinza kwePutty
Izakhono zokugcina amanzi kunye nokusasaza ze-MHEC zenza kube lula ukufunxa ngokupheleleyo isamente, izinto ezithatha indawo yesamente, kunye nezinye izinto, ziphucula amandla okubopha phakathi kwe-putty kunye ne-substrate, zinciphisa iingxaki zomgangatho ezifana nokuqhekeka kunye nokwahlukana, kwaye ngaxeshanye zenze ifilimu ye-putty ibe nkulu kwaye ihlale ixesha elide.
3. Iingenelo eziqhelekileyo ze-MHEC kuzo zombini iinkqubo
Nokuba zikwii-adhesive zethayile okanye kwi-putty powders, iingenelo ezipheleleyo ze-MHEC zibonakala kwezi zinto zilandelayo:
