Ngokuthuthuka okusheshayo kwezinhlelo zesimanje zokwakha, ukufakwa kwamathayela kuye kwashintsha kusuka ekudakeni kwesimende kwendabuko kwaya ekuthuthukisweniubuchwepheshe bokunamathela amathayili asekelwe kusimendeIzinamathiseli zamathayili ezisebenza kahle zinikeza amandla okubopha angcono, ukuguquguquka okuthuthukisiwe, kanye nokusetshenziswa okulula.

Phakathi kwazo zonke izinkomba zokusebenza kwe-tile adhesive,isikhathi sokuvulaingenye yezakhiwo ezibaluleke kakhulu.

Isikhathi sokuvula sinquma:

• Isikhathi esingakanani amathayili angabekwa ngemva kokusakazwa kwe-glue
• Ingabe amathayili asathola amandla anele okubopha?
• Ukusebenza kahle kokwakha ngaphansi kwezimo zezulu ezahlukene
• Ukuqina kokugcina kwezinhlelo zamathayela

Isikhathi sokuvula esinganele singabangela:

• Ukunamathela okuncishisiwe
• Amathayili angenalutho
• Ukuhlukanisa amathayili
• Ikhwalithi yokufakwa engeyinhle

Ngakho-ke, ukuthuthukisa isikhathi sokuvula sekuyiyona nto ebalulekile kubakhiqizi be-tile adhesive.

1. Siyini Isikhathi Sokuvula Se-Adhesive Yethayela?

1.1 Incazelo Yesikhathi Sokuvula

Isikhathi sokuvula sibhekisela esikhathini esiphezulu ngemva kokufaka inhlaka yethayela phezu kwesisekelo lapho amathayela asengafakwa khona futhi afinyelele ukusebenza okuhle kokubopha.

Kuchazwe kalula:

Isikhathi sokuvula = Isikhathi sokusebenza esisebenzisekayo se-glue eveziwe ngaphambi kokufakwa kwethayela.

ISIGABA SEMIBUZO EVAME UKUBUZWA (Ingxenye 1)

Q1: Siyini isikhathi sokuvula i-adhesive yethayela?

Isikhathi sokuvula yisikhathi ngemva kokufakwa kwe-glue lapho amathayili esengafakwa khona ngenkathi kugcinwa ukubopha okuqinile.

UMBUZO 2: I-HPMC ingasithuthukisa kanjani isikhathi sokuvula ithayela lokunamathisela?

I-HPMC ithuthukisa isikhathi sokuvula ngokwandisa ukugcinwa kwamanzi nokunciphisa ukulahleka komswakama kusuka kungqimba lokunamathela.

Umbuzo 3: Ingabe i-RDP iyandisa isikhathi sokuvula?

I-RDP ithuthukisa kakhulu ukunamathela kanye nokuguquguquka, kuyilapho i-HPMC iyisengezo esiyinhloko sokwandisa isikhathi sokusebenza.

Umbuzo 4: Kungani i-adhesive yethayela yoma ngokushesha kakhulu?

Izizathu ezivamile zifaka:

• Ukugcinwa kwamanzi okuphansi
• Ukukhetha okungalungile kwe-HPMC
• Izinga lokushisa eliphezulu
• Izimo zezulu ezomile

Umbuzo 5: Ingabe ukwandisa i-HPMC kungandisa isikhathi sokuvula njalo?

Cha. I-HPMC eningi kakhulu ingathinta kabi ukuxuba, amandla, kanye nezakhiwo zokusetshenziswa.

Ukwandisa isikhathi sokuvula ithayela lokunamathisela kudinga indlela yokwakheka elinganiselayo. Isu eliphumelela kakhulu lihlanganisa:

• Ukukhetha okufanele kwe-HPMC
• Ukugcinwa kwamanzi okulungiselelwe
• Ukuguqulwa kwe-polymer ye-RDP
• Umklamo ofanele wokwakheka
• Izindlela zokwakha ezifanele

I-HPMC isalokhu ingenye yezithasiselo ezibaluleke kakhulu zokufeza isikhathi eside sokuvula ngoba ilawula ukunyakaza komswakama futhi ithuthukisa ukusebenza kwe-glue.
