1、Insufficient foaming ntokuru

Nea ɛde ba:

(1) ɔhaw ahorow a ɛfa aduru a ɛma ahurututu ho no su pa ho;

(2) plasticity a ɛba fam a ɛwɔ rɔba ade no mu;

(3) ɔhyew a ɛkɔ soro dodo wɔ afrafra mu ne aduru a ɛma ahurututu no porɔw ntɛm;

(4) Wɔde rɔba no si hɔ kyɛ dodo anaasɛ ɛwɔ ɔhyew a ɛkɔ soro dodo mu, na ade a ɛma ahuru no bi yɛ nwini anaasɛ ɛporɔw;

(5) Ahoɔhare a rɔba no de yɛ vulcanization no yɛ ntɛmntɛm dodo;

(6) nhyɛso no yɛ kɛse dodo, na ɛboro nhyɛso a ɛwɔ mu a mframa a ɛwɔ aduru a ɛma ahurututu no mu ba no so, na ɛma ntokuru a ɛyɛ ahurututu no nnɔɔso;

Nneɛma a wɔde ko tia:

(1) hwɛ sɛ ebia aduru a ɛma ahurututu no wɔ bere a wɔahyɛ no mu na ɛfata sɛ ebia ɛfata;

(2) hwɛ sɛ ebia plasticity a rɔba ade no du gyinapɛn no ho, plasticity sua dodo ɛsɛ sɛ wɔde ka ho denam afrafra, ma plasticity kɔ soro na ama ntokuru a ɛbɛkɔ so ayɛ mmerɛw;

(3) Hwɛ sɛ ebia ɔhyew a ɛwɔ afiri a wɔde fra nneɛma mu no mu hyew yɛ kɛse dodo, sɛ ebia ɔhyew a ɛwɔ roll no mu no yɛ kɛse dodo, ne sɛ ebia rɔba no ahyew anaa. Wobetumi de rɔba nneɛma bi a ɛwɔ ɔhyew a ɛkorɔn a wɔde frafra mu de aduru kakraa bi afra mu anaasɛ wɔde foaming agent heavy industry aka ho;

(4) Ɛsɛ sɛ wɔsan de rɔba no kɔ baabi a wɔhoro no ma wɔyɛ ho adwuma foforo bere a wɔde kar asi hɔ bere tenten dodo akyi;

(5) formula nsakrae, hwɛ sɛ ebia ɔhyew a ɛho hia a ɛwɔ vulcanizing agent mu ne ɔhyew a ɛporɔw a ɛwɔ foaming agent mu no bɛn wɔn ho wɔn ho, na wɔne wɔn ho wɔn ho yɛ biako ma vulcanization ahoɔhare ne foaming ahoɔhare no hyia;

(6) yɛ nsakrae wɔ afiri no nhyɛso mu.

2. Nkuku a wɔde hyɛ mu a ɛnnɔɔso

Nea ɛde ba:

(1) Rɔba dodow a wɔmfa nni dwuma;

(2) Nkuku a wɔmfa nwie anaasɛ nkuku a wɔde di dwuma bere tenten dodo a wɔanhohoro, rɔba a ɛsen no tumi gyina ano;

(3) Abura no nhyehyɛe yɛ nea ɛyɛ den na sɛnea rɔba no tumi sen no nhyia, na mpɛn pii no entumi nhyɛ nkuku no atifi ma bere a wɔayi tokuru no adi awie no, na ɛma sintɔ ahorow ba;

(4) Mframa a ɛwɔ nkuku no ntwea a awu no ntumi nkɔ, ma enti rɔba no renhyɛ abura no mu ma, na ɛde gluu a enni ano no ba;

Nneɛma a wɔde ko tia:

(1) Wɔkari mmiako mmiako de hwɛ hu sɛ gluu nneɛma no mu duru te;

(2) ma rɔba no mu nsu a ɛyɛ mmerɛw no tu mpɔn;

(3) Sesa nkuku, ntease nhyehyɛe a mframa mframa ntokuru, nkuku nhyehyɛe, ne nea ɛkeka ho.

3. Tokuru a ɛyɛ ahurututu a ɛnyɛ pɛpɛɛpɛ (ɛsõ dodo anaa nketewa dodo) .

Foam tokuru no sõ dodo, hardness ne density a ɛwɔ ade no mu no nyɛ standard, tokuru a wɔato mu no bɛyɛ joint tokuru, micro tokuru no bɛyɛ tokuru ketewa, afã horow bi bɛhwe ase anaasɛ afã horow bi ntumi nkɔ soro.

Nea ɛde ba:

(1) foam agglomeration anaasɛ nneɛma nketenkete no yɛ mmerɛw dodo;

(2) afrafra a ɛnyɛ pɛpɛɛpɛ;

(3) nsuo a ɛdɔɔso a ɛwɔ aduru a wɔde bom, mframa anaa efĩ a wɔde afra rɔba no mu;

(4) Vulcanization a ɛnnɔɔso, kɔ so nya ntokuru wɔ nkuku no akyi;

Nneɛma a wɔde ko tia:

(1) hwɛ aduru a ɛma ahurututu no mu, sɛ ɛsɛ sɛ wɔde sieved phenomenon of agglomeration no a, ɛsɛ sɛ wɔbubu nneɛma nketenkete a ɛyɛ mmerɛw, frafra koraa (anaasɛ ɛyɛ tratraa) na ama apete pɛpɛɛpɛ;

(2) ne agent nsuo no ɛsɛ sɛ ɛkɔ soro dodo wɔ drying akyi, yi mframa anaa efĩ a ɛwɔ rɔba ade no mu, sɛnea ɛbɛyɛ a ɛbɛyɛ vulcanized koraa.

4. vulcanization a ɛboro so anaasɛ vulcanization a ɛba fam

(1) Vulcan a wɔde di dwuma boro so

General surface discoloration, eyelet ketewa, hardness kɛse, product no ano mpaapaemu, a efi adwumayɛ a ɛmfata mu, anaasɛ ɔhyew a ɛkɔ soro dodo, vulcanization bere tenten dodo anaasɛ adwinnade a entumi nyɛ adwuma, ɛsɛ sɛ wɔhwɛ sɛ ebia valves ne nnwinnade no wɔ ɔhaw ahorow, na afei wɔde adwumayɛ ho mmara no di dwuma katee.

(2) wɔ vulcanization ase

Sɛ vulcanization no nnɔɔso a, nhyɛso a ɛwɔ pore no mu no sõ sen akyi nhyɛso bere a afi nkuku no mu akyi, na sɛ rɔba no kɔ so ma ntokuru a, hann no bɛma ayɛ den kakraa bi, ahoɔden a ɛnyɛ papa na asɛe kɛse nea emu yɛ duru no bɛma ntokuru no apae. Ɛsɛ sɛ ɛhwɛ sɛ ɔhaw bi wɔ adwinnade ne valve no ho anaa, na ɛde adwumayɛ ho mmara no di dwuma katee.

Hyɛ no nsow: Foam nneɛma na ɛhwɛ nneɛma a ɛkyerɛ sɛnea nneɛma te so

(1) Density a ɛda adi sɛ ɛyɛ ketewaa no, dodow no ara na eye;

(2) mfiri ahoɔden taa yɛ 0.5-1.6Mpa;

(3) static compression daa deformation;

(4) sɛnea ɛyɛ den;

(5) nkɛntɛnso a ɛyɛ den;

(6) ɔbrɛ a ɛyɛ nnam a ɛkɔ so;

(7) onyin ho sɔhwɛ (digrii 70 * nnɔnhwerew 70; digrii 100 * nnɔnhwerew 24);

(8) ɔhyew a ɛba fam sɔhwɛ.
