Kungani upende oshisayo ancibilikayo ehluleka ukuhlanganisa? Indima ebalulekile yokuhlekisa kokuqala
Ukukhishwa kwesikhathi:2025-07-28
Ukunamathela okumpofu kokupenda kokumaka komgwaqo okushisayo kuvame ukubalwa kusuka ekulungiseleleni okunganele okungafanele. Nakhu ukuthi ukwenziwa kwe-Primer Pretrection kuqinisekisa ubumbano obuhlale buhlala buqinile:
1. Ukungcoliswa komhlaba: I-Primary Cuelit
Uthuli, uwoyela, noma umswakama ku-asphalt
ukhonkolo kudala umgoqo, ukuvimbela ukungena kwepende. Ucwaningo lukhombisa izindawo ezingcolile zinciphisa ukunamathela ngo-40%.
Isixazululo: Ukuwasha okucindezelwe kakhulu kanye nokuhlanza (isb.
2. I-Primer's dual Mechanism
I-Chemical Bonding: Ama-epoxy noma ama-acrylic primers angena ezindaweni ezinama-porous, akha ama-molefanelar bond nge-substrate kanye ne-hot-lyt resin (e.g., C5 petroleum resin).
I-Work Ansise: Izindawo ezinolaka (isb.
3. Ama-primers akhethekile wesimo sezulu
Izindawo ezinomswakama
Izimo zezulu ezibandayo: Ama-primers omisa ngokushesha (<10 imizuzu) Gwema ukuqhekeka okuhlobene nesithwathwa.
4. Ukucaciswa kwesicelo
Ukumbozwa: 0.2-0.3 kg
Isikhathi: I-Primer kumele yome imizuzu engama-30-60 ngaphambi kohlelo lokusebenza olushisayo olusebenzayo ukuze kusebenze abagqugquzeli bokunamathela.
Ithiphu ye-Pro: Ama-Primers aqinisekiswe yi-ASTM D913 anweba amamaki okumaka isikhathi ngeminyaka emi-3-5 uma kuqhathaniswa nezindawo ezingalashwa.
