Ikhonkrithi: IsiKhokelo esisiSiseko sabaQalayo

Ikhonkrithi yimathiriyeli eguquguqukayo kwaye ehlala ixesha elide esetyenziswa kuluhlu olubanzi lwezicelo zokwakha.Nokuba ungumthandi we-DIY okanye ingcali yokwakha, kubalulekile ukuba ube nokuqonda kakuhle ikhonkrithi kunye neempawu zayo.Kwesi sikhokelo sokugqibela sabaqalayo, siya kuxoxa ngayo yonke into oyifunayo malunga nekhonkrithi, kubandakanywa nokuba yintoni, yenziwe njani, iintlobo zekhonkrithi, kunye nendima ye-cellulose ether kwikhonkrithi.

Yintoni iConcrete?

Ikhonkrithi ngumxube wesamente, amanzi, iiaggregates (ezifana nentlabathi, igrabile, okanye ilitye elityumkileyo), kunye neentlobo ngeentlobo zezongezo zemichiza.Xa ezi zithako zixutywe kunye, ukusabela kweekhemikhali kwenzeka, okubangelwa yinto enzima kunye neyomelele.Amandla kunye nokuqina kwekhonkrithi kuxhomekeke kumgangatho kunye nomlinganiselo wezithako ezisetyenzisiweyo.

Yenziwa Njani Ikhonkrithi?

Inkqubo yokwenza ikhonkrithi ibandakanya amanyathelo amaninzi.Isinyathelo sokuqala kukuxuba i-samente, amanzi, kunye ne-aggregates ngomlinganiselo ochanekileyo wokudala intlama.Intlama ke ibekwe kwi-mold okanye formwork kwaye ivunyelwe ukuba lukhuni okanye ukunyanga.Emva kokuba ikhonkrithi iphilisiwe, i-mold okanye i-formwork isusiwe, kwaye ikhonkrithi ilungele ukusetyenziswa.

Iintlobo zeConcrete:

Kukho iindidi ezininzi zekhonkrithi, nganye ineempawu zayo ezizodwa kunye nokusetyenziswa kwayo.Ezinye zezona ntlobo zixhaphakileyo zekhonkrithi zezi:

1. Ikhonkrithi yamandla aqhelekileyo: Ikhonkrithi yamandla aqhelekileyo lolona hlobo luxhaphakileyo lwekhonkrithi esetyenziswa ekwakheni.Inamandla oxinzelelo lwe-2500-5000 psi.
2. Ukuqina okuphezulu kweConcrete: Ikhonkrithi yamandla aphezulu isetyenziswa kwizicelo apho kufuneka amandla aphezulu.Inamandla oxinzelelo lwe-10,000-20,000 psi.
3. I-Concrete eKhanyayo: Ikhonkrithi ekhaphukhaphu isetyenziswa kwizicelo apho ubunzima buyinkxalabo.Yenziwa kusetyenziswa iiaggregates ezikhaphukhaphu ezifana neshale eyandisiweyo, udongwe, okanye isileyiti.
4. I-self-Compacting Concrete: Ikhonkrithi yokuzimela luhlobo olukhethekileyo lwekhonkrithi ehamba kunye nokudibanisa ngokwayo, ngaphandle kwesidingo sokungcangcazela.
5. I-Fiber-Reinforced Concrete: I-Fiber-reinforced fibers luhlobo lwekhonkrithi oluqiniswa ngeefiber, ezifana nentsimbi, iglasi, okanye i-synthetic fibers, ukuphucula iimpawu zayo.

Indima yeCellulose Ether kwiConcrete:

I-Cellulose ether yongezelela imichiza esetyenziswa ngokuqhelekileyo kwikhonkrithi ukuphucula iimpawu zayo.Yipolymer enyibilikayo emanzini enokuthi yongezwe kumxube wekhonkrithi ukunyusa ukusebenza kwayo, ukunciphisa ukufunxa kwamanzi, kunye nokwandisa amandla kunye nokuqina kwayo.

Ezinye zeendlela apho i-cellulose ether inokuphucula iipropathi zekhonkrithi zezi:

1. Ukuphuculwa kokuSebenza: I-ether ye-cellulose inokuphucula ukusebenza komxube wekhonkrithi, okwenza kube lula ukubeka nokugqiba.
2. Ukuthotywa kwamanzi okuncitshisiweyo: I-ether ye-cellulose inokunciphisa ubungakanani bamanzi afunxa ngekhonkrithi, okwenza kube nzima ukunyathela imijikelo yokuqhaqha kunye nokunciphisa umngcipheko wokuqhekeka.
3. Ukunyuka kwamandla kunye nokuqina: I-ether ye-cellulose inokunyusa amandla kunye nokuqina kwekhonkrithi, iphucula ukuchasana kwayo ne-abrasion, impembelelo kunye nokuhlaselwa kweekhemikhali.
4. I-Adhesion eyomeleziweyo: I-ether ye-Cellulose inokuphucula ukubambelela kwekhonkrithi kwezinye iindawo, ukuphucula amandla ayo okubopha kunye nokunciphisa umngcipheko we-delamination.

Isiphelo:

Ukuqukumbela, ikhonkrithi yimathiriyeli eguquguqukayo kwaye eyomeleleyo esetyenziswa kuluhlu olubanzi lwezicelo zokwakha.Ukuqonda iimpawu zekhonkrithi kunye nendima ye-cellulose ether ekusebenzeni kwayo kubalulekile kuye nabani na osebenza ngekhonkrithi.Ngokukhetha uhlobo oluchanekileyo lwekhonkrithi kunye nokubandakanya i-cellulose ether kumxube, unokuphucula ukusebenza, amandla, kunye nokuqina kwezakhiwo zakho zekhonkrithi.
